I know a fellow boater that owns a body shop, he told me once that Rustoleum Industrial works good but it has to be Industrial. I haven't tried either one.
I suck at painting and never been happy with a paint job from a spray can. If you can remember the picture of my .12 is was finished with epoxy. I used pigment added to the epoxy for color, I used black and red. Here is a process that I used if anybody wants to try it. Mix good epoxy with lots of pigment, brush it on with a foam brush or paper towel ( I like the paper towel there cheap and you don't have to clean them). I do one side at a time so it will flow out flat. Lay it on smooth, wet sand it with 600 on a flat piece of wood or something, use 400 if you need to remove alot. but don't sand through just the high spots and keep doing this until it's flat. Usually 3 times will do but you can keep going until it's perfect. Careful on the edges they are the hardest to keep color on. As you get close to perfect on your last coat you finish sanding with 1200 or 2000. The finish will still be dull. To get the gloss rub epoxy on with a paper towel and let it sit a minute and then with a clean paper towel buff it like you would shoe polish. Don't touch it and let it dry, it will give you a nice glossy finish when its dry. I use the same process to finish CF when I have to sand on it. I just don't add color.
The benifits of this process are, it's cheap, I can do it my self, no over spray, it comes out perfect, each time you add a coat and block sand it you can keep the riding surfaces on the bottom sharp.
It sounds like alot of work but I have finished a couple of boats using Dupont Emron sprayed on at a body shop, by the time you spray and wet sand the good primer twice and after the Emron is shot, there is still rounded edges on the bottom of the hull that need to be wet sanded to sharpen them. Still alot of sanding. It coast almost a $100 in paint supplies.
