Thinking of putting another mirror in the bathroom and was thinking of
using this mirror-fixing adhesive. I've seen in another thread that
you can remove it using fishing line or some such material, but can
you actually get the tiles back as clean and pristine as they were
before (when er' indoors changes her mind)?

Also I want to put the mirror between two windows but have the mirror
slightly overlap the (very light) architrave on each side. This would
mean the mirror would be about 2mm off the wall. Would this adhesive
still workwell enough at that distance if I put a serveral good blobs
behind the mirror?
