i accidentally pulled out my visor last night while trying to pull out a piece of velcro inside the helmet. i had my visor in with a 2 part epoxy, guess it didn't hold too well. anyway, since it's out i'm planning on putting a clear coat on the helmet to keep the paint job from getting screwed up. i have a can of krylon low odor clear matte finish. is this basically the same thing as the testors dullcote? or would the testors be a better buy? also, would jb weld hold the visor in better than the epoxy did?
