Just like the title says. Just got a replacement for my missing window trim (rubber and metal) and need to fasten it down. Stays in place with a push fit, but pops up when the window goes up. Will any epoxy work, or should I use something less permanent in case it needs to come off in the future?

 

You might try adjusting the tangs a bit...it is supposed to just press in place and stay. If you do use adhesive use a modest amount of clear silicone, which can be removed without too much difficulty.
