My rear view mirror fell off last week and since I have tried the following:
1. 3M Stick Mount from the Auto Store
2. 3M Heavy Duty Mounting Tape
3. Heavy Duty Glue from Auto Store
4. 3M Stick Mount (2nd one) from Auto Store
5. Super Glue
6. 2 Part Epoxy - Gorilla Products

Nothing held my mirror up, WTF am I doing and/or what kind of wizard voodoo magic occurs when you have your windshield replaced?
