Supermarine Paint. I got a quart of the Revolution 1000; gave some to Carla and we're both gonna run some tests on it; I'm thinking about using it on bottom of my boat after I got it soda blasted. It's one part, guaranteed for 10 years underwater, can be applied with a roller, and is evidently very tough stuff once it cures. The only problems I've heard of is, because it depends on oxygen to cure, it can be slow to cure if you put it on too thick. It needs to be put on in thin coats. I'm going to try some samples using 1/4" nap roller in next couple of days; will let you know how it turns out. Denny
