I have standard glass windows sandwiched between applied metal trim to give the appearance of divided lites. I would like to customize the divisions by removing some of the metal trim (to give the appearance of a six over one window). However, the metal trim is stuck to the glass by some kind of adhesive. Anyone know how to remove the adhesive? I know that if the glass were broken the entire pane would have to be replaced, so how do I get the metal trim off?
