I'm building my first fiberglass kit and, of course, I need to score all mating surfaces to ensure a good bond with the epoxy, but how much scoring is needed? I attacked my switchband and coupler first by hand with some 80 grit and, dang!, this stuff is hard to make a dent in!
I can definitely feel that it's a rougher surface now by touch, but visually, you can't really see any difference in the sanded vs. unsanded areas unless you've got a bright light on it.
Any thoughts on what optimally prepared surfaces look/feel like? Or, better yet, can anyone share a pic of one?
(and, yes, I did try to search for previous threads with similar info but struck out)
