I am in the final stages of preparation for painting the bottom of my sunfish. Hopefully the snow will melt and temperature will com up to the point where I can get back to work. I looked at an Interlux product called Perfection yesterday. It is a two part epoxy paint. Although it is designed for over the waterline, it has an anti abrasion qulaitiy that I think is good. The boat is not kept in the water. The bad news is that is costs $58 a quart. Since I got the boat for free, I don't object to the cost, but if there is a product with a known track record, I would go that way. I have a compressor but have never spray painted anything. I anticipate using a roller or brush. Another question: my sail is probably at least as old as the boat (1968). What performancve differences would I anticipate in buying a new sail. Thanks, I have always received great advice through this forum. Dave G.
