The plate, mat, and glass. What do you use to seal them and how do you do it?
I have tried J-LAR, Filmoplast P90, Lineco Frame Sealing tape, and even Filmoplast T. My favorite so far is the frame sealing tape because it is a solid chemical barrier. The frame sealing tape has an aluminum backer which helps to create a nice vapor barrier but it has its problems.
My biggest problem is getting the tape to stay attached to the edge of the glass. Because the framing tape is opaque I can’t wrap the tape around over the top like I can with the J-LAR. I’m not even that crazy about going over the top of the glass with the J-LAR though. If I had package preservers then it would be a different story… anyone know where I can find some or how to make them?
