View Full Version : Bottom paint question - 1979 SNS
10-24-2013, 11:12 AM
So I brought my boat to be wet sanded/buffed, re-seal rub rail and repair fiberglass boarding platform. Guy seemed very knowledgeable and has 38 years of experience but said that I had blistering on the bottom and that I should use barrier paint so the blistering doesn't get worse.
The boat is kept on a trailer and is usually only in the water on weekends, has anyone else had this problem or have experience with barrier paint?
also - if anyone has a fiberglass boarding platform for sale please PM me.

I thought blistering only occurred when the boat is kept continuously wet. If you keep the boat on a trailer and not in the water, it should not need anything. Did a previous owner keep it docked for a long time?

Is the blistering limited to the area of the hull that contacts the trailer bunks?
I had blistering from my boat lift. Apparently the bunks were holding water. I changed from carpet covered bunks to plastic covered to prevent this issue.

The previous owner probably kept it on the water, the blistering is mainly around the shaft/strut/rudder area in rear and isn't extensive....haven't noticed it along the bunk lines but we'll see what the guy says who is doing the work
Basically I'm trying to decide whether to barrier paint the bottom since boat is usually on a trailer. Will this blistering eventually lead to the bottom rotting away?
Thanks for replies.

Assuming that you don't use the boat in salt water, I would NOT bottom paint it.
We took our boat to the local fiberglass guy, he said the blistering would subside over the winter while sitting on the trailer (different bunk location) and that as long as we did sometime to correct the lift bunks holding water against the hull we would be OK.
He was 100% correct. Pictures would be helpful, but since you don't leave the boat in the water and the blistering isn't significant I would just monitor at this point.

Thanks, that's what I figured but wanted to make sure since I'm spending a lot on the hull/gelcoat and don't want to need a new bottom in the near future....
