I do not have a cover for my Laser and so when someone was grinding nearby, hundreds of tiny flakes of steel landed on my deck. Of course they immediately began to rust, but that was easily cleaned up with some fiberglass cleaner. The problem is that the steel flakes are still stuck onto the deck, because they were hot when they landed so likely melted on. Is there any sort of chemical treatment I can use to dissolve them but not the gelcoat? I do not want to have the expense of putting a new gelcoat on the deck.
Thanks for any suggestions.
