i jsue cut one out of the race car, i have done it with the 90 degree knife made for glass, it works amazing on the rear andside windows, but the urethane stuff is tough as nails, i HIGHLY recomend paying to have it removed, i wish i had, i got the top and the bottom cut with the tool, but the sides wern't playing, i ended up just busting the dam thing out, powdered glass everywere, don't do as i did
