I've had very good luck with good old WD40 . My luck is enhance by the fact that there's a can living in my tool bag.

You can find it in any auto supply store. It can be used on fiberglass and I found that it didn't harm the gelcoat. It comes in a 4oz spray bottle. Spray it on and leave it on for a minute or two and wipe off with a very very soggy-wet terry cloth and then hose down well. Have some premixed Boat wash in a bucket to folllow up to remove any of the residue from the Super Clean. It was also the fastest thing I've used to remove the sticky adhesive left when taping off the boat for painting.

Is goof off safe to use on the fiberglass? Should one avoid the wood trim? Today we cleaned and waxed it and want to add the finishing touches. Also we noted the post about the M 15 for sale at Sacramento State Univ Aquatic Center. That is where we learned to sail. Valerie Gates Mistral
