I have a 1979 Aquasport 19 Family Fisherman that I'm doing some gelcoat repair on. Having a ****ens of a time getting the color match close enough to suite me. Boat is kind of an off-white/cream color. I need to find out what base colors went into the original batch. I've been trying combinations of white/black/brown and getting nowhere. There must be something else. I sent a note to Aquasport, but haven't heard back. Can someone pass along a little advice? Thanks.
