I went to a local composite repair supplier to get a bit of white gelcoat to put over a repair i did with epoxy and carbon fiber. The salesperson was adamant that the gelcoat would not adhere to a cured epoxy laminate and said it might even eat a hole in the boat. Obviously I know gelcoat repair has been done over cured epoxy many thousands of times the world over and it works. The sales person refused to make the sale. Am I missing something here? I plan to rough up the cured epoxy with sandpaper to get a mechanical bond with the gelcoat. Any wisdom appreciated!
