Did you use one part or is this the first painting of your hull? We roll and tip pioneers are the future for many of countless gel coat faded fiberglass boats. A tough two part finish will be the longest solution, but it will still be a relatively short life compared to gelcoat. It's not going to make financial sense to have a professionally sprayed topside for many older boats, though, like mine.

I was inspired more than a decade ago by the ancient wooden boat maintenance program. Because wood is always moving, it makes no sense to use the newer two part, long-lived coatings(except over glass areas). Wooden boats are usually coated often and simply. Least labor, cheap coatings, more often-many seasonal topsides.

The upside, despite being the oldest boats around, they look new,... often!(downside, cost, a yearly enamel brushed on).

I think I could get more years out of my topsides paint, especially if I went with two part, if I were more careful. But we're hard on the boat's topsides. A lot of rough docking, constant dinghy abrasion, and lot's of rafting up. Plus, most every season I get a phantom ding or two on the mooring, from unknown boats - objects.

It will be interesting to see this new stage in old boats. The 35-40 year point when gel-coat is toast is here for countless hulls. A pro applied two part looks best, but, you can buy many of them for less than the cost of that job, which keeps going up, as the value of the boats go in the other direction.
