And that is motorcycle helmet before anyone starts I'd read somewhere a while ago that it's not a good idea to use vinyls/stickers on helmets but can't find where it said this and the reason why. Does anyone want to jump in on this and add some of the ways you guys do modify them as I wouldnt mind some subtle vinyls.
