3m Paint Protection Film (Clear Bra) Please click this link for more information.
http://www.3m.com/The following are a few pictures of the 3M Clear bra. This should be installed by your dealer, or a trained professional, as its pretty easy to screw up. If you do decide to do it yourself, make sure you buy a roll of the clear film, as the pre cut kits never fit right. Basically the install of this is the same as installing window tint. First the installer makes sure that all the surfaces are clean and dust free. Then the installer cuts to film to the desired size. Once this is done, he/she will spray the surface which will receive the film with a water / alcohol mixture. Next, they lay the film on the car and get all the bubbles out. After this, they may use a heat gun or a hair dryer like type of tool to help aid in drying the alcohol / water mixture. Here is a few pictures I took when the car was dirty. Its kind of hard to see, but if the car was clean, it would be impossible to see with a camera.
