On that note, Paint Thinner also works well as a solvent for butyl and other things (acetone, methanol and Isopropyl did not). I had some winch handle holders that were attached to a sheet of velcro that had a thick gooey glue to attach it to the bulkhead. Paint thinner worked best to soften the glue so it could be removed by scraping and rubbing. Goo Gone did nothing. On another note- I read in Practical Sailor about using Glass Cooktop cleaner (Weiman) on fiberglass for stubborn stains. That worked quite well on everything I have tried it on, so I keep both on the boat now. Dave
