I'm having a slight problem with some windows on the boat, which slide down to open, and up to close. To close the window, there's a metal piece that straddles the top of the glass, with a lip on the inside that you use to pull up the window. The problem is, many of these pieces simply pop off when any pressure is applied, making the window much more difficult to close. It appears in the past some kind of rubber piece was put under the metal, and the whole business held together by some kind of adhesive, which is worn out. What would be a good adhesive to use that would re-stick the metal pieces to the glass (or rubber on those windows swill with a rubber piece). I want something strong enough that if I put a stick against the lip to keep the window from being opened from the outside, a potential burglar couldnt just pull the window out from under the metal piece and get in just the same. Thanks for any help!
