Hi, I would clean both surfaces and use a new piece of 3M two sided mounting/moulding tape on it.[/quote
Bob's got it.
Get as much of the old tape off as you can and clean both surfaces good, I think most have delt with the problem at some time. 3m does make some super sticky tape, get the industrial strength stuff.

So when is this..."old enough to know better" supposed to kick in?
