hey all...i just removed the visor sticker with goof off (which btw is EXCELLENT for removing scuff marks and stuff)....but now the spot's a little darker than the rest of the visor....it's not entirely visible but i would like to know how to get rid of it...i thought it was leftover adhesive but i used goof off again but nothing happened...and i don't think it's cuz of a dirty visor or anything since it's darker there than on the rest of the visor....any comments?
