Wow that's some shiny paint! When I attach glass in, I first use Elmer's White Glue and tack the corners and the middle of the glass to the body. After that, I use Testor's Clear Glue for glass (The one that is white and then drys clear and has a purple label) to go fully around the window. I paint the headliner before I install the glass, so I don't have the chance ever of getting the paint on the glass. Hope to see this under glass soon! Cheers!
