Hi all,

Well, this boat seems to be cursed! I applied a coat of Pettit epoxy paint yesterday. Today it seemed dry enough for a second coat. Nope! Crazed and ran. I'm depressed.

Any ideas, short of letting it dry and sanding it down to start over? I guess I didn't leave enough time for the first coat to cure.

Sounds like it was put on too thick and had skinned over . There is nothing you can do but to let it dry completely and sand it back as you have said. Each coat of those one part paints should be "nearly" semi transparent to work and cure well. It should take several coats on a new build to have a solid color base. I know many will probably try to feed me my hat over this but thinner is better including the final mil thickness. Thickly applied paints shrink for a long time and it has been my finding that is what causes most premature coating failures if the surface was prepped to spec.

I put it on with a brush, should I have sprayed it instead?

I don't know the boat or what the substrate is but it is usually best with the one part paints to roll it on and tip it with a brush. The roller assures a nice even thickness of paint.

There is a bunch of videos on that page that you can look at also.

Hi all,

Well, here is a picture of my "20 foot" boat. The physical length is only 16 feet, but she looks much better from 20 feet!

Every project is a learning experience. I hope I don't make the same mistakes next time. I'll probably make new ones.
