Thank you for you consistent hard work making these videos! Remember the more you do the more people want, do please take your time and avoid burn out. Great Job. LadyD Cheers
I wrote a lot of notes while watching this, stopping and starting the video. After watching hundreds of fibreglass builds and repairs this past year I finally get what I need to know about the various resins as I begin my transom and deck rebuild. There's no way to say Thank You strongly enough. I've planned to start with repairing the helm, start small, make small mistakes.
Glad the videos are helpful! Thanks for watching
Dude, you definitely need a PROJECT FARM collaboration lol
I like it!
😂
Man, I’m ready for another boat, build series keep them coming!!!
That's the plan!
I used vinyl ester for wrapping and adhering the engine and tranny mounts on my Shamrock, which were then gelcoated. The only drawback is the short shelf life compared to polyester. It has to be fresh, and used promptly.
Some brands have better shelf life than others. I have been very happy with the vinyl Ester we have been using recently.Overall vinyl Ester is a great option where you need strength and waterproofing, and also want to finish with gelcoat. Thank you for watching and commenting!
That really helped with the difference between choice
Great video, thank you!
Glad you liked it!
Great video!
Thanks, glad you enjoyed it!
Thanks a good way of explains and a good video with ur fine voice.

Thanks for being so thorough on your videos
Glad you like them!
Great video thanks
Glad you enjoyed it!
Good content, most people don’t know, or understand the difference in resin, nor do they know how many are actually out there, thank you
Thanks! I agree, I think most folks just don't realize how many option there are when it comes to resin selection. I hope this video helps!
👍🏼FGRP's strike exciting inspirations of building things.
Enjoyed the demonstration
Thanks so much!
Good morning, excellent lesson!!!
Thank you!
Another thoughtful informative and well laid out video. Wishing you continued growth!
Thank you!
Joe I really like how you go into depth. Thanks for all the time you put into the videos hope all your clients catch big ones
Glad you are enjoying the videos and thanks for watching!
Good video Joe !! Any help you give us is appreciated
Glad to help
Very interesting, and very good content.
Glad you enjoyed it
Capt Joe, Another awesome video! This video really compliments our recent Patreon conversation! I appreciate how much your channel is helping me with my project boat!
Glad that the videos are helpful! Thanks
Capt Joe and family Thanks for your comment just wanted to ask y'all some of these resins especially polyester say not to use below the waterline but not planning on leaving the boat in the water will be trailering home after each use some of these resins have their own secrets hopefully y'all may no what they are referring to in these products? Y'all take care moving forward!
Great content. I’m glad you’re doing this I’m not afraid to do some of these repairs on my own now!! Thank you
Glad to help
Another awesome video Captain Joe, your content is excellent. Much appreciation as always 👍🇦🇺
Thank you so much 😀
Thank you for the video...
Welcome!
Would really enjoy seeing a sheer test. Appreciate your time to create and share your professional opinions on products and techniques!
Great suggestion!
Thanks for a great channel👌🏻👌🏻👌🏻 Going with the vinyl ester💪🏻 Longer potlife as a bonus👌🏻
Awesome! Thank you!
Putting a new deck on my boat very informative channel big help doing plywood glassed on both sides. thanks
Glad to help!
Great job Captain Joe. Your Videos are the best I have came across. Having the top quality Cameras and an actual camera man really gives you the Over the Top quality Videos. I would love to see an All about me video with the history of your Boating family. How much of the boat building does your family still do?
Wow, thanks! Glad you are enjoying the videos. I appreciate the video suggestion, and hope to do something along those lines soon.
Cutting and reshaping a SeaRay 4’ swim platform to fit my Californian. Watching and learning as much as possible before I choose materials. Now I’ve got to do some homework on vinylester.
Thanks for watching
Glad I found you a few weeks ago.... at 68 and downsizing a 5000 sf cabinet shop and doing a total wsstoration of a '69 42 Chris Craft commander.... Foam toe rail and with faux wood finish.... final 24 git grinding tonight before final glass ,, thanks for your channel!!

Glad to help, and best of luck with your project.
THANK U FROM MIMS FL, YES I AM WITH PATREON, AM REPAIR BOATS ,SMALL THIS IS ALARGE HELP.
Glad to help, and best of luck with your project!
The man is on other level🔥 he even knows the story overseas very informative 👍👍
Thank you very much!
Thanks for all the useful info, if possible please do a bonding test of the 1708 with diffrent resins to plywood and old cured fiberglass like in a old boat restoration.
Thanks for the suggestion
This is just the channel I need, stationed out in Japan and starting a flats skiff for fishing here, was wondering if y’all could cover fiberglass on foam board trying to cut the weight down as much as possible. Keep the awesome vids coming!
Very cool! I will try to add some foam core construction content to the channel for you. Best of luck with your project!
I like that you found some resins available to the diy market.
I’m A polyester resin man all the way having been in fiberglass industry years. The cost for diy resin is crazy high compared to industrial pricing.
I guess you don’t remember the days when we had to use paste or powder BPO catalyst in sticky vinylester resins ( derakane) , ever since they came out with the AME2000 VE resin that used MEKP the VE world changed!
The things I don’t like about using epoxy is
it’s much slower too work with ,
it’s very expensive in small lots,
It’s more toxic ,if you get it on your skin , espically when sweaty you can get sensitive to it permanently! Not good!
Good video!
Cheers Warren
Thanks for watching, and really appreciate your thoughts and feedback!
It would be awesome if you tried to glue the different resins. Im about to do some repair on the outside of the keel of the boat and standing between vinylester and epoxi. thanks!
Best of luck with your project!
Joe thank you for the effort you put into your videos ,much appreciated. I have a quick question I had damaged the bottom of my boat on the ribs no holes would it be best to repair with 1807 or 1808 and use an polyester resin and then mix up a little apoxy resin and just apply over the repaired area to prevent water intrusion
VERY GOOD INFO! I've been waiting for this to figure out what to do about replacing a 15' fishing boat floor. I was leaning towards epoxy but vinylester seems to be a better choice... as is the tacky polyester so I can put a grit paint down on as the last coat. Looking for a SIMPLE VIDEO on that sort of deal. High Tide boats are notorious for needing new floors after about 30 yrs (lol)... I've got one that is pending and now I feel better about what to do.
Glad the videos are helpful! Best of luck with your floor replacement.
Awesome videos , i have been binging on them. Are you still planning on doing a key west style t top video/series? And which rod holders did you use on the side of your console on the 29?
Thanks! Yes, I am still planning a hard top build series. The rod holders are from T and H marine. I hope this helps this helps and thanks for watching!
Hey capt joe, just want you to know loving all the vidios learning a ton just picked up a 1993 sea ray express cruiser 250 sat for awhile came from lake michigan spent the last 2 years in lake O in florida. never been in salt water it only has 486 hours motor is sound hull is solid from research specs say it was made with vinylester resin wich is a good thing I suppose watching your vidio with the can of beans coud not be more true. the boat had a alot of decorative panels plywood wrapped with foam and vinyl and carpet glued to the glass I ripped it all out.one of the shelves had resin rolled on no rot, the other not coated rotten I want to cut the shelves off close to the hull and grind as close as I dare my question to you is can I use a laminating resin with mat on the curves I also want to epoxy some rips of plywood for mounting some under gunnel rod holders to mount on due I need to cure the poly before I go over with epoxy and 1708 or can it be tacky sorry for the long story just want to do it right. Thanks dan
Hey Uncle Joe! Another great video. I order my resin from US composites. Little cheaper than the others I have found. Ordering site is a bit archaic but the products are top notch.

Hey man! Thanks for the suggestion.
Can you tell us where you get your red catalyst dye? Keep up the great videos love watching!!
I buy it from a local fiberglass distributor, but I will see if I can find a online source for you guys that I can put a link to below the videos description. Thanks for watching
Great video thanks for the sharing information. I got a question where you get the red dye I would like to get some for myself. Thanks appreciate it.
I get the red dye at our local Advanced Plastics in Elberta, Alabama. Most fiberglass distributors should also have it if you ask for it. Hope this helps. Thanks for watching!
Tanks
Great video capt. Joe! I am in the fiberglass industry as well and am trying to get into mold making and I was wondering if you could offer any information or maybe a video on the whole process it would be greatly appreciated!!
Thanks! If you look back through the channel in our boat building series, episode 7 shows me building a console and leaning post mold. You might find that interesting. I am planning to build a hardtop mold for our custom 29 very soon, I will be making detailed videos of the whole process for you guys. Appreciate you watching!
Thank you! I appreciate it! Keep up the good work!
After watching this video I should have used a polyester resin and saved some money on my most recent project. Due to my inexperience I always buy epoxy resin for my projects thinking it is the best. I will certainly make a more informed decision on projects in the future. Thanks
Glad to help, and best of luck with your projects!
This has been very interesting. I'm planning on building a kayak very shortly. After seeing this video I now know what resin I will use. While watching this a thought came to mind, and I would like your opinion. This will probably be be very different than what is typical. Have you ever thought of applying a coat of contact adhesive to a plywood boat, and then lay fiberglass into the contact cement as a first layer?
Glad you are enjoying the videos! No, I have never seen that done before. I think I would stick with resin personally.
Love the video. Good information! I have a question, which resin would you use on automotive ? I have some wheel wells I'm going to rebuild with fiberglass.
Thanks, glad you enjoyed it! The vinyl Ester is the best overall in my opinion. Hope this helps and best of luck with your project!
Awesome video. Vinyl Ester it is! Any issues using it over polyester putty?
Thanks! The vinyl Ester and polyester are completely compatible. Best of luck with your project!
Epoxy can take 6-10 days to “fully cure” depending on ambient temp. But once it finishes it is much harder. Polyester will continue to cure for months (and shrink on a micro level) which is why it tends to have less adhesive properties. If I had to guess I would say that epoxy was 2-4 days old. Your videos are awesome! I will be subscribing to the patreon here shortly
Thanks for your thoughts
Also some epoxy need to be cured in an oven. I hope this is not one of them.
Was reading through past comments and would also love a video on fixing spider cracks. That seems very intimidating. Just a thought...maybe you can find someone with an old "project" boat to donate to the shop as a way to demonstrate different repairs/techniques. Best way to show us how to fix things might be to start with something broken haha.
Thanks for the suggestion! We are working on getting a project boat in the shop soon for you guys. I appreciate you watching and commenting!
Thanks for the information.
Which one do you recommend for automotive exterior body kit applications
Glad you are enjoying the videos! The iso tooling resin and the vinyl ester are really good. Epoxy could also work, but you would have to use epoxy based fillers and primers if you choose to work with the epoxy. I hope this helps, and thanks for watching!
I may have asked a while back....
What would you use to cover a boat or camper made of foam board
I am going to build an 8 foot long by 36 inch high and 40 inch wide box. I think out of 3/4 inch plywood. What is the best supplies to have for this?
Could you talk about the shelf life of the resin. I have used vinyl ester before and that has a short three month shelf life if I remember right. I have some west system epoxy now for a over two years will it still be alright to use?
I cant find any videos on repairs on seadoo cm tech hulls skin or what to use to reinforce the inside
Maybe a post with FGWH with how they see their products being used.
Thanks for the suggestion
Do you have a video on flotation foam installation methods? Thank you.
I plan to make a flotation foam video soon for you guys. Thanks for watching!
Could you do a video or comment on boat flex allowances, areas and necessity? I am in progress on a transom replacement from rotten wood to Coosa on a 25' plus twin outboard glass bracket center console boat. I want to terminate my stern floor liner directly to the transom (via glassed in coosa bracing). It used to have a liner to transom gap, but I want to do floor drains via directly cut slots straight out the back. The previous gap there (pvc pipe out) was a major source of my leak that rotted the wood. If I bond the floor directly to the transom am I killing a necessary flex and may end up cracking floor, stringer or transom? I'm also planning to do a permanent glass and bolt bond of the engine bracket to transom. You have by far the best show on boat works and I appreciate your longer and encompassing demonstrations and explanations. I am doing the work and you are helping immensely. Huge fan here. Thank you!!!!!!!!!
Sounds like a great project boat you are putting together! We almost always glass floors to transoms, as well as glass splash wells and other structural parts together. There is always going to be some flex in fiberglass parts, but in my opinion you would want to minimize it. When parts flex alot, they usually fail at some point. There are several videos in our custom 29 boat building series that shows us glassing floors and splash wells, etc to the transoms. I am sure these videos would be helpful.Of course every boat is different, and you have to decide what is best for your boat. I hope this helps, and thanks for Watching!
@@FishBumpTV Appreciate that info. I've actually owned this boat 22 years and hope to have it another 22. I've been watching your 29 boat build but sometimes, like any other series on Ytube, it's hard to get the videos in sequence and find myself fishing for it. I know you can't usually make a link to the next video because at that point you haven't shot it yet, but maybe you could always have a link to the previous video so we know when we skip to far ahead. Had my semi pro glass guy helper with me yesterday and today (at $100/hr) and he's asking me how I've come up to speed so well and challenges me on some of it. It's because of you man. I wasn't fully on board some of his work and I went forward at 5 AM today before he got here and made some nice advances, like more glass structure in the transom and bracket areas where the bolts run through. And today we worked together and glassed and bolted the bracket to transom. It's better than ever. Many thanks and when I get through this I promise to send you some thank you $ too if the boat survives the beat down test run. You are awesome, keep it up!!!
@@tmc.318 Glad you are enjoying the videos! I recently numbered the boatbuilding series with episode numbers in order, so I hope that helps with any confusion. I Really appreciate you following the channel, and your positive feedback is very encouraging! I wish you the very best of luck with your boat project.
Great video. Would the epoxy resin be more impact resistant?
Thanks! Yes, usually in my experience the epoxy and the vinyl Ester are more impact resistant.
PROJECT FARM COLLABORATION! He'll take care of the science you take care of the glass.
Haha maybe so!
Good, Video, any of these are compatible with construction foam board? I guess Epoxy? What about Acrylic Resin?
Thanks! Epoxy is likely to be the most compatible.
very helpful vedio
Thank you very much!
Is there ever a scenario where you would use different resins as you build up layers? you mentioned having 10 layers on the floor of your build, would you ever mix as you build up those 10 layers?
We usually laminate with only one type of resin, but sometimes you will do a vinyl Ester skin coat. I just wanted to show that many of these resins are compatible with each other, and can work together if that if what you had to work with. Thanks for watching
What would you recommend to use on the bow and walkway of an older boat? 1974 Trojan f25
I really like the vinyl Ester as a all around quality resin, it does many things very well. Thanks for watching!
Im trying to fix a transom that has delaminated in a small area. I was thinking of injecting a resin into the split from the top and then clamping. Would you choose vinylester or epoxy? Love your channel!
They could possibly both work. I might lean towards epoxy on this one though. Just be sure there is not any moisture in the delaminated area or nothing will stick. I hope this helps and thanks for watching!
@@FishBumpTV Thanks again for all the help. You are awesome!
Which resin do you think a sailboat made in 1967 was used? And what should I use for repairing. Thank you
Most likely it was built with a ortho polyester. The vinyl Ester resin is a really good choice for all around repairs. Many people also like epoxy, but it is not usually recommended that you use gelcoat over epoxy resins. Hope this helps, and thanks for watching!
@@FishBumpTV
Yes thanks, another question what is best fiber glass fibers for deck to hull joint repair 1708 or 1808 in 6 t0 8 inch strips
I want to do a webbing/splatter finish on my current project. I don't have a sprayer and don't want to invest in all the necessary equipment and additives for a small project. I bought a can of Montana Marble Effect Acrylic spray paint which will produce a similar webbing effect. Will acrylic paint stick to gelcoat? Thanks.
I don't know if that could work or not, I have never tried doing that before. You could always do a test panel and see before doing the whole thing. I imagine even if it does stick to the base gelcoat that it would not be as tough as gelcoat splatter in the high wear areas. Hope this helps and thanks for watching!
Can't beat Total Boat products for all your fiberglass needs !!!
I have fiberglass hydrohoist tanks I'm repairing (cracks and chips). I know that you mentioned that you don't use finishing resin, would it be necessary for my job? I plan to epoxy prime and bottom paint the tanks after the repairs are complete. Thanks for the help, your channel is super informative!
Why are you using bottom paint?
@@jbaasdad The are submerged in the water 24/7. I figured bottom paint would be the best option. Is there something else you would suggest?
The vinyl Ester resin is the is going to be be the best for that application in my opinion. It bonds very well when used in repairs, it is compatible with csm or mat fiberglass and it is a great water and moisture barrier. I hope this helps and best of luck with your project!
I love the vinylester but the shelf life is really short comparatively speaking.
Yes, compared to epoxy resin that is true.
Hi do you have any tips on how to strengthen a transom on a small fiberglass boat? I have already clamped and fiberglassed two pieces of plywood on the actuall transom but i need strength lengthwise ! Is there any solution like some supports or something?
Every boat is different, but adding some support in the corners, or from the transom to the floor may be the ticket. You might try to look around for simular boats and see what they have for transom supports. Hope this helps, and best of luck with your project.
I don't think the styrene-based resins were fully cured. Likely they would have performed more similarly to the Epoxy if they were fully cured. I think also for repairs, the secondary bonding strength of Epoxy gives it the upper hand and why most DIY folks tend to use it more. The only downside is for repairs when gel coat is involved.
Thanks for your thoughts
What do they use for kit cars or other fiberglass cars?
It is hard to say for sure, as different companies could choose to use different resins. It is most likely a polyester resin, could be a isophthalic. Hope that helps and thanks for watching
@@FishBumpTV Thank You! I look forward to future videos.
I am disappointed with the results of the epoxy resin.
Did you use a fiberglass that don’t have the binding agent that make it incompatible with epoxy + of the same weight that the fiberglass you used for polyester resin?
Yes, I was also surprised. The 1708 biaxial glass used in the video is compatible with all types of resin, including epoxy. The fiberglass for all of the test pieces was cut from the same stock piece of 1708, and all of the pieces were left to cure for the same amount of time under the exact same conditions. I just did a very basic strength test to show you guys how they reacted when put under stress, but feel free to do your own testing. I Hope this helps and thanks for watching!
Thank you for your answer. I’m surprised that there is fiberglass that can be used for both epoxy and polyester (fiberglass for polyester contain a binder). I though polyester resin need this binder that is in the fiberglass. Could you talk about that? Is there a need to add this binder on the fiber glass before adding the polyester resin on such fiberglass?
The format of your videos is great by the way. Good videos.
@@nico-bf1kr The csm is the only fiberglass that I am aware of that has the binders in it. There is another type of csm that has a powder binder , that does work well with epoxy resin. Apparently that type is not available in the U.S . I will try to make a video on this topic for you guys. I hope this helps, and thanks for watching!
@@FishBumpTVThanks! I will be happy to watch that video! 👍
Vinylester all day. Much better working time than polyester. It’s a shame you didn’t show the gelation and curing time.
It’s a shame you haven’t made 100s of hours of content, hours editing videos on your own time using and sometimes wasting expensive materials to help other people learn.
Thank you Mike
