I installed the headlight armor in the lighter of the two smoke options the other night. There is still a lot of bubbles in it because the car has been sitting in the garage since its been raining lately. I just put it outside today to sit in the sun. On a scale of 1 to 10, I give the install about a 6 in difficulty. Its just hard to get the headlight armor perfectly center. It took me about an hour to install. It gives the car a whole lot meaner appearance.
