I tinted my foglights with that stuff on my old '02 LS. I got it at Pepboys. I have also seen it at Walmart. You'll need atleast two cans. The first few coats actually had a purplish look, the more coats you put on the darker it gets. Make sure you you spray it nice and even or the depth of the tint will be off and get a blotchy look with some areas darker than others, since its transparent it doesnt apply quite like paint. I practiced on an old headlight from my wife's car.
