Didn't know tints had an extra clear film layer that had to be taken off before fully placing the tint film 😂 i done messed up no wonder it wasn't sticking right do all tint rolls have it ???
You probably tinted many straight flat windows with no curves because without the heat gun to “shrink” the film you wouldn’t be able to get the film to hug the curvature of the glass let alone forever pressing down finger.
