Polish side glass?

Do it on a cool or cold (shady) day, take your time. Use your hand/fingers to touch the glass to make sure it's not getting hot. Use a spray bottle of water to keep it cool. Work over a large area ( blend, like when you're doing body work) so that you don't dig/make a valley/depression. Be prepared to make a mess as the polishing compound goes all over the place. If you do it with the glass in the car you have to tape off everything with paper or you'll be cleaning that stuff out of every nook and cranny for months!! You're clothes will get stained so wear and apron. Please don't ask how I know???
