OT - I have looked through our technical library for information on refinishing fiberglass, but alas all we have is literature on modern composites! Perhaps Net Wisdom can keep me from going down the wrong path and recommend a good book.
I've got to decide whether to strip the Kelmark's paint or sand it down, and how to do it right. I'm inclined not to use fiberglass paint stripper because of a bad experience once - it hardly worked at all and I can imagine what a mess I could make sanding it improperly.
