How do I get the WD40 off.
I just used Isopropyl on my helmet for cleaning it up before applying a decal, I also used it on the bike to clean up the left over adhesive from the stock decals.try a heat gun or hair dryer to get off the sticker, it doesn't take much heat. = then a little bit of WD-40, cooking oil, peanut butter will also do it. I don't think the WD-40 will hurt a thing, I've been using it for many years, never had a problem, it's the fish oil in WD that does the work. Helmets are tough, they have to be. Wipe it off with a towel, then a bit of cleaner, then shine it up with your favorite wax, it'll look like new. Oh, stop worring.
Yeah, I don't know what solvents might have what effect on polycarbonate. I found this:There are two kinds of helmets out there: fiberglass and polycarbonate, usually Lexan. Some polycarbonate helmets have the color molded in and therefore no protective layer -- with these I'd be a little careful what you put on them, but WD-40 or Goof-Off should be perfectly safe. Fiberglass-shell helmets are painted and have a clear coat top layer, so anything you would use on automotive paint (which is about anything) should be OK.
The only solvent I would avoid like the plague is acetone.
