So I was glassing some wooden fins a buddy made, and I screwed up. I forgot to put a layer between the glass panel and the fiberglass cloth, so now my fins are glassed onto a window pane. I was able to pry the cloth/resin on the perimeter away from the window pane, but am struggline on the flat edge of the fin. I have been using a razor blade and paint scraper to try and pry them apart or chisel away at the glass, but with minimal success. Has anyone else ever made this msitake or have any recs on how to remove the glass and save the fins?
Try putting ice on the ‘‘glass side’’ to hopefully cause it to contract enough to enable a successful separation of the two elements. Or a hair dryer, or heat gun, for a similar effect.
