I just came across this product, and wondered if anyone has tried it. Its on the Marinebeam website that Stu recommended for LED lighting. Its called Un-hesive, and looks very interesting. Here's the link:

No affiliation - just thought I'd pass it along.
PS gave it a check mark

But it's "unavailable"
