I just used the 3M kit on my headlights and WOW did it ever work !! I think it was
THEBULLET83 that said he had used it and his lights looked great, said he paid 30 bucks for it. I checked Advance Auto & they had it on sale for 17 bucks ! I forgot to turn the pixels down on my camera, so I couldn't upload the before pics but they were baaaad !! Really dulled and yellowed. I was even able to squeeze our Tahoe's lights out of the kit. they give you plenty of sand paper-500,800grits then a wet sand disc then a buffing compound and a drill mounted arbor with a sponge face. Hell, I'd pay the 30 for it it's a lot cheaper than a new housing.
