Windshield Mylar install Question

Can one of you show, or better describe what you mean by mitering the mylar at corners or cutting it at a 45 deg. angle? Thanks


I just cut a notch in the Mylar and Filled the crack with sealant, It's not a perfect angle but from a distance it looks fine.

One other the gasket I got are not a perfect fit their are a few gaps here and there. I guess if I worked with it some it may have fit better, but I'm OK with it.
