Auto Mask:
Porsche invented the fabric auto mask ( the so-called car bra) in the late sixties, when the factory still individually road tested every car, and because they used the local roads around the factory, a temporary fabric mask was put on the car, to protect the new paint.
It was never intended to be permanent, because no matter how careful you are, no matter how clean you keep your car, the fabric bra will eventually cause a tremendous amount of paint damage as they trap dust and road grit and vibrate in the wind. They also cause uneven fading because the paint underneath them is not exposed to sunlight like the rest of the vehicle.
A more viable alternative is a pressed, polished thermoplastic vinyl (X-Pelâ„¢, Amour Glove, 3M) made from an optically clear 12-Mil clear film that has been treated not to occlude (yellow) its virtually indestructible in normal use and adhererâ€â„¢s to the cars paint surface. Available in custom, laser cut templates that are available for virtually all car models, and many parts of the car, clean and maintain its surface with Z-8 Grand Finaleâ„¢ Spray Seal) or a plastic cleaner (Plexus® Plastic Cleaner, Protectant and Polish). Ensure that there are no surface imperfections before installation; do not use a foam pad / rotary buffer / abrasive compound on the plastic surface. Tape the edges of the auto mask when polishing the vehicles paint.
