Hi CQKiter,
I have always just taken my epoxy boards to a professional surfboard shaper/manufacturer to repair. They get to get all itchy, sticky and dusty and do a mint job. I just hand over a few bucks and get my board back stronger than it was.
Bloody good deal I reckon!
I am happy to fix little dings and such with Epoxy repair kit, (available at all good surf shops), and fix all my own poly board repairs, but if it's a nice board and it warrants a nice finish or is a major repair like folded nose, rolled fin plugs etc, I leave it to the pro's.
Good winds,
