Jim, you are right and I realize most of the thread is about the other windows. However, a few posts mentioned the windshield and you know how it is . . . . sometimes unintended consequences result from good intentions. Nobody has mentioned fire in this thread so I brought it up. BTW, once while I was flame-polishing a Lexan edge, it caught on fire. Lexan is flamable!
I agree with Tom's post about running over glass with $2,000 (today's prices) worth of tires. I just wish there was a better non-flamable substitute.
