that stuff will be a biatch to get off the headlight housing without damaging the lense. can you post up a pic? I'm hoping you don't mean 3" thick.
I installed clear film on the lense for protection.
np, I like how they have colored or tinted film for the headlights and foglights. a bit of tint would look good with dark paint. I installed some lamin-x on my rocker panel, but my front bumper was done by a 3m installer.Thanks for the link to the Lamin-X headlight covers, Suzieque!
WD-40 would work, but you need to be careful not to use too much.WD-40 will probably get it off. Or a Mr. Clean Magic Eraser (it'll take anything off). It's a mild abrasive so be careful, but the chemicals in it will get it off quick!
