I just threw out two Polyform F5 $100 fenders that I cleaned one time with acetone. At first they seemed great, but after a month in the sun they got sticky. Neither 303 or wax kept the stickiness from coming right back for more than a few weeks. Then some dirt got on the sticky part. This left dark marks on the hull that only acetome would clean (which doesn’t hurt the fiberglass but does strip the wax completely)
From the MSDS, this product is mostly acetone. New fenders and a machine buffed Colinite wax job cost a lot more than any cleaner.
