How to protect glass from scratches
Method 1: If you are tinting a glass door in a high traffic area such as an industrial warehouse, or a door that requires a lot of heavy equipment moving through, it is possible to minimize scratches if the customer requests it. Tint the glass as normal, and then you can go over it as normal with either 4-millimeter clear safety film or anti graffiti film. Anti-graffiti may be better since it has a lower tack. It goes without saying that having to remove this film later will obviously be a lot more difficult, and you won’t be able to just remove the outer layer and tint again. Instead, you’ll have to remove both of the layers completely. This might end up being really expensive and time-consuming if you have a repeat client.
