Our man Fred is back with another painting video, his sense of humour is well needed on a monday afternoon, thanks Fred
A good epoxy seals the metal like a chemical plastic wrap. It bonds to 80 grit, sealing from moisture. 2k primer, body filler all absorb water, so no wet sanding. Shoot your high-build, sand with acrylic blocks, apply filler after metal work. If grinding to bare metal to stud weld, re-apply spot epoxy. Then filler, glaze, primer to perfection. Apply epoxy when paint ready and paint. Spray 3 coats of inter-coat clear often called flow coat but actually double clear. Wet sand with 1k, 1,3k and clean. Now comes 2-3 coats of European style clear called high solids. Then sit aside for a week to allow inter-coat to shrink & off gas as it shrinks before wet sanding. Once high solids is sprayed, it may not need more than buffing. You are done! Remember, additives for "UV" a, b & c proactive chemical package rises to the top! Wet sanding removes this protection. This is why a double clear or "Flow Coat" is desirable. Buffing does not remove UV protection. My best long term shine comes from no sanding just buffing. And wait 30+ days before adding a ceramic coating. Like concrete, the clear has to cure by off-gassing and shrinking. High solids clear shrinks less, leaving little or no orange peel as it off-gasses leaving a tough deep clear finish. This how Ryan Evan's does it at Counts Kustom's and many others. Extra time, more material, charge for it, but enjoy the results. DK, Retired; ASE Master tech since 78.
So very cool to see the project coming together! Excellent work and thanks for the tech explanation.
I was really surprised to hear about the pot life on epoxy primer. I’m used to things setting up so quickly that this seems like less pressure to get something sprayed. Good call on the material data sheet. Too many people these days don’t bother to read any instructions and then wonder why things don’t last. This is true not for just paint but all sorts of materials. Thanks for another great video!!
Always enjoy your paint job videos - explained so well. 🙂
Thank you for sharing your knowledge and experience with us!
Gotta see more videos on this 944! This is a job mine is needing soon so that would be great motivation!
Fantastic advice, thank you Fred , I’ll be using your advise on my next project 👍
As someone looking to repaint my truck for the first time, it's helpful to hear that you can stack another primer on top of the epoxy. Thanks for the info.
SPI is my go to primer. Love it. Great video
New DIY subscriber here with ProLite guns, great informative video!!! Great job with all the in-depth details, very valuable since I need it. I look forward to more videos from these guys!
SPI products are high quality ! Just finished using there products on a engine bay . Highly recommend. Customer service is spot on .
Interesting video, like your presentation style.
I know epoxy primers and paint are used on boats. Always figured if it's good enough for a boat it should be stellar for a car. Fred's confirmation makes the idea credible! 👍
I've used the SPI epoxy for a few projects. Great products! What about when you burn through the primer and need to put on another coat before you spray high build? Do you go back down to 80 grit on the bare metal spots?
Nice! Great work.
hey great video. I've a question. Could I use heat to reduce flash time? and what temperature I should to use?
Did not know there was a difference between Epoxy and 2K. I used 2k about 13 years ago on the car roof and all of a sudden, catastrophic paint failure down to the metal. I will use epoxy this time. Lots of good info for me.
all right, brother. was going to do a budget paint job on my e30, but you've convinced me to order some SPI =)
Nice!
@@UWrenchTVwhen you put epoxy primer on do you put 2k primer over it and if so how many coats
@@jermaineenglish5732yes. Like he said, read the data sheet. It will tell you what you can coat other products from their lineup. It also gives tons of other crucial info, like what pressures to spray at.
Also, PPG Shopline series EP only gives you 3 days to reshoot with 2k Primer, or you'll have to scuff it again. So read each data sheet!
1. EP over bare steel and body work I normally do 2 coats.
2. Then coat with a 2k high build sandable primer. You can do 2 coats. Then block sand. I don't go any higher than 400 grit. While some go to 600.
3. Wipe down VERY well multiple times with wax & grease remover and non lint cloths, until no more residue is on the rag.
4. Right before srpaying the paint, wipe down lightly with a tack rag to remove any dust/lint/bugs.
5. Spray with color coat as many coats as you prefer.
6. Run rack cloth.
7. Finish with as many Clear Coats as you prefer.
What particular degreaser do you recommend after sanding before applying epoxy primer? Also, when sanding the rust off the metal, do you recommend finishing it off with a fine high grit sand paper to get it ultra smooth or it’s not necessary? Thanks!
I'm an old guy that learned with nitro-celious lacquer in a Binks gun. This stuff makes an incredible foundation for a really good job.
Solid points !!!!
Using SPI epoxy primer on an aircraft I’m building, 2k urethane sealer over and a single stage paint , he is right on on all the excellent working aspects of epoxy.
Too many people skimp on the prep work and it shows.
You spray SPI 2k primer over the SPI epoxy primer? Was it the High Build Primer? I enjoyed the Video
Thanks
Good vid !
can you put on on before bondi
Yes bondo over it
Why not a acid etch primer

How long can a car stay outside in just epoxy?
11 days
Is this primer better than Eastwood's primer
Much better 👍
I’m spraying the SPI epoxy primer with a HVLP turbine system and a 1.0 gun tip. Lays down as smooth as a baby’s behind as they say with very little overspray.
Subscribed and Liked.... but I'm definitely not gonna comment!!
Right?
killer brah
👍🙂
Your channel rocks!!!!!
I hear George Costanza could have used less shrinkage
👍👊
Gave it 45 seconds then couldn't take it.
Yer I'm hearing ya, I was going to bail about the same time but hung in there and ended up with some interesting and useful content.
He a crack head
After first 5sec I understood your comment.
Close talker is in your face. But use "PI", "PI". No called SPI! Jess..
Epoxy....yay!
I almost gave in to the....Epoxy nays.
i'm glad your shirt has your name- that way you won't wear other peoples clothes
When you run a business it helps the customers remember your name.
You've got good content. Please stop with the silliness.
This is like a kiddie show, a little too childish for me. I dont understand why these guys do that nonsense i assume the majority of us are grown men and would like to be spoken to like grown men.
A 944 is also galvanized steel. That should last forever :)
The car is mine and i got it from a friend who daily drove it a few years on the east coast. It is impressive how little corrosion there is on it. With the job Fred is doing it well last a very long time!
Why so much filler on the fenders of the 944?
It’s actually very thin and he fixed a very shitty repair.
That fender is nothing, the other side was like an excavation from an old repair.
