That's a good question I've wondered myself. The first (proper) search result for this Google search
(not the videos) leads to Whitestone's answer here
Note that I quickly gave up on my first attempt - I think I had it misaligned or something, and I was able to pull it right back off, but that was immediately and without attempting to cure it. I don't know how long it would stay easy to remove without curing, but Whitestone's directions I'm sure apply to when the glue is cured one way or another.
