I've used Bon Ami for years to really clean windows for aplying Goldleaf singage, cool. So I figured I'd use it to clean the new to me truck windshield, before aplying rain ex, well it scratche the hell out of it
Must be some sort of soft glass or there's a film on the extrior of the windshield???
Anybody with a clue or knowlege, Bummer.
