AAR Glass is the worst i've ever used. weak, wavy. junk.
Glasstek has super strong straight glass. (if you buy street weight) I did my last car with their bumpers, fenders and hood. That car was so straight no one even knew it was all glass. The stuff took very little work to get it right and on the car.
My AAR hood is a train wreck. And it was bought quite a few years ago.
