Removing Cetol
No matter how careful you are with Cetol (or any other finish, for that matter...) it always seems a few drops find their way onto the white fiberglass. Here is what I've done: after trying a bit of acetone(which sometimes works, sometimes not), I tried fiberglass paint remover -- used very carefully and not left on the surface very long. Only mediocre success with that. But since I only had a bit of Cetol here and there -- on the non-skid, no less -- what really worked was taking an artist's brush and dabbing a few bits of white boot stripe paint on the offending Cetol: bingo, disappears....
