[T3] GPS to windshield?

[Jim Adney]

This is a pretty generic question, but I figured some of you out 
there must have a good answer for it:

What's a good way to keep my GPS suction cup stuck to my windshield? 
I've been using spit, but that only holds for a few days. There must 
be a decent sub that sticks well but is still easy to remove from the 
glass when I want to take it off.
