ive never used it or sprayed it. i was going to spray my front bumper with it but i never got around to doing it. when i was working at the bodyshop i was going to get some and spray it on a scrap fender just for kicks. i kept forgetting about it and now i dont work at a body shop anymore. maybe someone else has seen this stuff or used it. its just another option i thought i would through out there.
