I had success with it for a while on my handle pole, then I shortened the pole and screwed up the paint, so switched to ace epoxy enamel. Its held up great. Even though the sides of the bottom touch only the water, it may be peeling because the sides are going through the water fast and aggresively, unlike the handle pole. If that makes sense.

Wet, what was your temp and humidity if you recall? I used both white and now the black rustoleum appliance epoxy. I sprayed it while 85+ degrees and let sit for 2 days. my bottom was sanded with some 160 grit and acetone wiped down. then sprayed off with compressed air. it is hard as nails. I remember most of your fx1 build was in the somewhat cooler season no? sand it down and you "might" be able to use some dupli color adhesion promoter.. don't quote me.. read up on it. Ive used it for a lot of plastics and trim with good results. here is the white...

ya the air temp was probably in the 50s or 60s at the time and the humidity was high because we had a ton of rain. I'm sure that didn't help me at all....its comforting knowing that you have had good luck with it. Maybe if I sand it with a coarser grit during a hot dry day I might get some good results? I was using the same rustoleum stuff.

If I am not mistaken, Appliance paint is meant to be used on metal surfaces............ I used on it some forks on a mountain bike once and it was incredible strong............

Best I found for hull bottoms was Single Stage Urethane paints. That stuff is strong.

I was worried about that but decided to go ahead with it since I had read several threads on here with people suggesting it.

I sprayed mine with gel coat. Buddy sprayed his with auto paint. The paint grabs the trailer bunks like hot glue. It's unbelievable how tacky it grabs.

This ^. I used appoxy on my SJ and dragging off the beach is way tougher than gel coat skis. My SJ took help while my heavier Blaster slide like it was on slides.

Otherwise stuff is great, easy to touch up, cheap and durable. Just prep well and lay coats as the can instructs and all should be well.

I had good turn out with the appliance epoxy. I think your issue is you sanded it too smooth. 400 grit seems high. I roughed the bottom of my hull up with 100 grit and sprayed with no primer. Still holding up great. Worked well in the bilge also.

I would question a one part epoxy.

Yeah... I don't believe it is actually a bisphenol-a group epoxy. It's closer to a regular enamel. "Appliance Epoxy" is more about the marketing than the composition. I personally don't care for it due to the long cure times. Although it does build slightly higher than regular enamels.

Maybe a spray can 2k single stage. I have no experience with them though. They are one time use urethanes that you activate in the can. They will probably bond better, but I can't speak to their scratch resistance.
