Re: Interlux perfection/ bottom paint
Clancy, Most copper-based antifouling bottom paints have a flat finish, and has a course texture due to its great thickness and density. It also comes in only a few colors, but you can usually blend colors from the same manufacturer, to come up with a custom color.
It will therefore be very hard to match top and bottom. There is a "Shark white" bottom paint, which blends pretty well with regular topside paint, of a matching color.
