Twelve years ago I painted my 20' Spectra with Awl Grip marine LP, using a roller, in my front driveway. The paint still looks very good today even though it has never been wet sanded, rubbed out, or even waxed. Cost was around $120 total, used less than a quart of red and a pint of white, plus catalyst, reducer, and accelerator.
I invite you to come over and look at it since you're local. I have enough white paint laying around the shop for you to do your boat. You'll just have to buy some epoxy primer and roller sleeves.
PM me if you're interested.
Cheers, Mark
