I finally worked up enough nerve to attempt to install my Lamin-X kit over my headlights. The product installed over the small, oval, flat turn signal (?) light covers easily but installation over the headlight covers was impossible. I followed the directions to the T working from the inside out. The top inside of the headlight cover isn't a problem, but I couldn't get it to flatten out down over the outside of the cover. I kept ending up with two large, narrow, wrinkles or puckers (with bubbles around them) that just wouldn't flatten down.
The manufacturer suggests heating it with a blow dryer but no amount of heating would get rid of those wrinkles. Eventually, I decided to cut away about a quarter inch from the top of the one wrinkle which smoothed it out perfectly but it looked like I had a crack in my headlamp, so I ended up tearing the stuff off and throwing it away. I didn't even attempt the second headlight. Another aggravation was that the product was supposed to be precut to fit all the lights but it was too big for every one of them and required a lot of delicate trimming around the edges.
I am going to contact the manufacturer tomorrow. I will let you know how it works out.
