How to protect a mirror frame for later easy caulk removal
I am recessing a mirror with a painted wooden frame above my bathroom vanity. The painter says it needs to be caulked all around to look seamlessly built-in. Is there something I can put on the mirror frame (silver metallic paint) now that will make it easier to remove the caulk without damage to the painted finish if I want to remove the mirror later on? Maybe some kind of acrylic varnish? I even wondered about petroleum jelly or candle wax. Thanks for any suggestions!
