A large scratch has appearing on my tinted visor and I've got no idea how it occurred other than it happened between arriving and leaving work on Monday. Part of the scratch is directly in front of my left eye and is quite annoying, I'm starting to mentally flitter it out but it occasionally comes back into focus and annoys the hell out of me. Does anyone know any tricks at repairing the scratch? Deb suggested toothpaste today but thought the scratch was probably too big. Do you just polish the visor with the toothpaste? Any other ideas?
