What is the best method of de_greasing a painted lure prior to coating with epoxy, I am suffering the dreaded crater effect in my coating and I am convinced it is grease spots causing it.

I honestly don't believe just-painted-and-dried acrylic has any grease on it. The fisheyes I see in epoxy are usually caused by not brushing the epoxy down enough onto the underlying surface. If a spot isn't wetted out by epoxy, it will void as it cures. It can also happen with oily woods like cedar if they haven't been undercoated with an oil based primer. However, if I wanted to degrease acrylic, solvents are obviously out. I'd spray it with a mild Mean Green or Oil Eater solution and rinse it gently with cool water - done after the paint is THOROUGHLY dry. No rubbing!

Thanks for your reply. I have never really given much attention to the way the epoxy is applied or the type of brush used. I use a very soft brush for application which is a very smooth and light method. Should I be using a stiffer brush and work the coating harder also should I be applying lighter coats and more of them rather than the heavy coat I am using now ???
