Ok, I finished painting the boat a while ago, but only finally got around to posting some pictures.
The paint looks much better than I anticipated. It is painted with two coats of medium blue on top and two coats of blue glo white on the bottom. This is on top of two coats of Pre-Kote primer, which were sanded between coats. I did not sand between topcoats. I prepped the body by sanding it with 220 grit sandpaper, cleaning it, and rubbing it with an acetone soaked rag. I applied the primer with just a foam roller, and the topcoats with a roller and tipped with a decent quality brush.
I was unimpressed at first because even a couple of days after painting the boat, the paint could be scraped with a fingernail, however, after a week of sitting it was much harder. The paint held up well when I bumped up against a dock, banged into another boat, however, I accidentally submitted it to much more last weekend. I tried to dock up against a dock with a 15 knot wind blowing me into the side of the dock, and the paint got a few scratches from that. I also flipped the boat and had to right it against the rocky side of a lake after being pushed up against it. That caused a few scrapes as well.
Overall though, I'm still very pleased with the result. I Think that even gelcoat would have gotten some scrapes with that punishment. The same would likely go for the more expensive one part polyurethane paint. At least with this paint its really easy to touch up the scratches and not be too noticeable. I definitely think white on the bottom was a good call, as that's where the boat will take most of the punishment.
