2011/2012 We painted the hull and all the metal on Hobo plus re-gelcoated the house and fly bridge. We had just spent over a year in Panama and Central America where it rained a lot. Other boaters that had painted had issues with the 2 part polyurethane paints bubbling and lifting on the decks where water pooled or didn’t drain and/or under deck carpet or coolers/deck boxes. That’s one of the reasons opted for the gelcoat plus I knew the guys that would be working on it.
Fast forward 7 years. I wish we had painted the entire boat. The gelcoat was more expensive to do since it is more labor intensive. It’s harder to keep up and imho harder to repair. We also have a few areas where the application was thin or the crew removed to much while finishing. As far as the standing water, yes that can be an issue but then again we haven’t had the 75-100” of rain we saw while we were in Central America. The gelcoat still looks good but it's hard to beat modern paints.
