I used this process to repair over 100 blisters four years ago and have not had a single blister since. THANKS for sharing this technique! Previously I had paid thousands for a "blister job" in a yard but all the blisters returned in less than a year.
Thank you for taking the time to show the process. I live aboard in northern Lake Michigan on a P26 and will be doing a little bit of this (probably much more than I think) at the end of this coming fall, during the winter. Very clear info and delivery, much appreciated.
Thanks for all of this, Wow. It is rare to see product comparisons and you did a great job explaining it all. I have a 32' Sidleman that will be needed this work soon and this helped ! Thanks for sharing your experience.
Considering the age of this video, how did the repairs hold up? Did you get a few seasons in before blisters reappeared - have they reappeared? What was the total cost estimate? I was thinking of buying a boat, should I purchase pre-1973? Like a Cat-30 made in 1969? Or could that still have blister issues? Lastly, I hear blister develop from leaving your boat in long periods of time. I was thinking of having a boat similar to yours, in water, year round (nice climate, west coast of British Columbia, Canada). Do people do that without much issues, assuming they have a good boat to begin with or are not afraid of doing repairs every couple of years? Sorry for the barrage of questions, and thank you for the video - thumbs up to this and teachers!
h Thanks for your comment! The blisters have not reappeared since. The boat has been actively cruising in the Bahamas and was recently hauled out for bottom paint. Sorry I don't know the cost, we made the video but it's not our boat. The project entailed mainly grinding and epoxy filler, there was a lot of labor the owner did himself. As for boats, we'd recommend contacting owner's groups and forums which can be very active. They may be the most helpful in determining blister issues as they tend to be well documented among older boats.
Hi, thanks for your comment! In our experience yards have always allowed work. It is always good to ask about painting and sanding near other boats and be very thoughtful and clean about it. They may put you in a specific area of the yard if you are working. Some marinas can charge for every little thing so it would be good to price out a "work order" with them beforehand. There will be a charge for moving jackstands, lift, launch and sometimes even water. We wish you the best!
Was looking at your other videos and saw you state you respond to some questions.. but that was a few years back.. Any rate if you are still active, we are wondering if other ways of fixing blisters exist? Thanks in advance if you answer.
Hi, thanks for your comment. We don't have any updates on this topic, we never had further blisters after the project. Wishing you the best with your project.
Thanks for your videos! I'm actually working on an old fibreglass canoe and have been looking for some good advice on repairing it. I plan to strip off the gel coat and now use the interlux product. My canoe looks like it has had some structural damage in the past with poor repairs (the fibreglass patches were never smoothed back). What grit grinding discs and sanding paper would you suggest to get the canoe ready? Before and after applying the interlux? Thanks, Dave
Thanks for your comment. What we like to do is dial the customer service number on the Interlux can, they are really knowledgeable and can give you specific advice for your project.
Do a lot of marinas have places for you to work on your sailboat like this? I'm assuming this is at some sort of marina. Do they charge just to take the boat out of the water, and rent those boat "jack stands" I guess they would be? Lol Thank you! Love your vids btw. Definitely love the day in the life videos. :)
Check with locals that have done "DIY" in that specific yard. Many Yards have official rules they must state, but more lenient practices. Be hyper-courteous to everyone in a Yard; its a tough place to work and owners are usually very concerned about their boats. I think of a haul-out like Intensive Care; some boats need exploratory surgery, some get through easy, some won't make it out.
+tomterahedrob -- Nowadays osmotic blistering isn't really an issue on quality boats; the cause and cure are better understood than they were four decades ago.

So the interlux putty is better than west system with 407 or 406?

This is why I like Aluminum boats. Fiberglass and gelcoats are not waterproof after they
have been in the water a long time.
A moisture meter is very handy for locating and measuring the dry out process.
Good info.

and thanks for the info on the 70's
I thought you could not put west systems resin over polyester resin hulls?
I believe you can put gel coat or epoxy resin over polyester resin
Why not just have an epoxy gelcoat to begin with?

Why not fiberglass
