I'm planning to use West Systems 610 epoxy to fill in a few scratches/gouges in the bottom of my boat. Does anybody have any experience with this product to support giving advice on better ways to surface prep, apply the product working overhead, max/min thickness, working time, cleanup, etc... My main goal is to seal off the transition between the gel coat and the glass without getting epoxy all over the areas around the scratches. I remember CasaCola advising me to just swipe a credit card across the gouges, but I'm thinking there may be a little more to it. ????
