Windshield film

#1

What is the best windshield film for protection and where do you get it?

I’ve tried this 4x and I can’t seem to get the stuff applied optically clear. No matter what I did, in the end it was awful. Since then what I do is put a strip of the stuff at the top and the bottom of the windshield, leaving a ~8" section in the middle for my eyeballs. Eventually a rock hits the unprotected glass, but it’s been a pretty good compromise.
