Speaking of the pre-cut film, they are a disaster in my opinion. The fact that they are pre-cut makes the process even more frustrating. instructions say touching film leaves finger prints, and also says the film must be heated/stretched to form to the contoured surface. The handling tabs they put on them rip off because of the sharp edges cut into them. The film is easy to crease, and is semi dull in finish. I've tinted for several years professionally and found these to be a pain in the a$$ to apply
nicely. With two sets of hands and a large piece of tint you could get the film to lay down decently, but it will not match the paint gloss up close. I ripped them off and choked it up to a learning experience.
