I painted my Hypalon Achilles with the expensive 2 stage
paint. It absolutely ruined it. The main problem is that the paint is matt, so attracts the dirt, and picks up every stain and scuff. It looked great for a day or two, but then began to look increasingly horrendous.
Drag the dinghy across any rough surface, and the paint scraped off, back down to red hypalon.
My
advice is to save your
money.
