When I began this business I was primarily protecting glass and mirrors. The business grew to include the interior cabs of stainless steel elevator doors. It took five years using 3 different glass scratch removal concepts, I combined the best of the 3 modalities to make my own system that actually removes scratches from glass with NO distortion. For 24 years we have used a 6 mil, three ply film called Vandal Shield. We custom cut Vandal Shield to fit any gas pump, ATM, or elevator lens. This will protect them from graffiti scratches.
