just decided to call Raka, where I get my epoxy from. The tech guy there said to just use paint, latex exterior house paint is what he said that Larry tells people. But the tech recommended a marine epoxy primer and paint from West marine or similar. He said there's no reason to mix pigment in with the epoxy on the wet-out, but that some people will mix pigment in on fill coats to give that added protection (in case somebody drags something across the deck, etc).
