Removing rear view mirror tab on windshield?

[RICKDIZZLE]

So I got a new custom rear view mirror and the tab that gets glued to the windshield is different then my current. What is best way to remove the current tab attached to the windshield and what is the best/correct glue to use to affix the new one. Thank you!

You can get glue at most auto parts stores.
I've had a couple fall off on hot summer days lol.

Mine is really really on there..like doesnt wanna move at all. Also ive heard a lot of the automotive store glues are poor quality. Anyone have a brand that is proven to work?

I used 3M stuff when I had to glue on the tab for the 84 H/O. I think that was around 2004 or so? It hasn't fallen off yet.

Mess with it and that windshield will crack...

I tried to "save" one once. Cost me the windshield. Unless you can find some chemical that will dissolve the glue- leave it alone.

it'll come off with a razor blade, you can work the blade under it but take your time or you'll crack the windshield. Use a hair dryer first to heat up the adhesive

They fall off when you don't want them to, can take a bomb blast & not move when you want it to.

Agreed, if you still have the old mirror, mount it to the existing tab and use as a handle. Heat up the outside of the glass with a heat gun (don't overdo it and melt it) and the existing adhesive should loosen up enough to grab the mirror and wriggle it off by gently twisting it back and forth.

Florida sun beating on your windshield seems to loosen them easily....especially when you don't want them to fall off.
While we're on the subject. Does anyone recommend a good product to glue the tab on? The Permatex stuff that I use seems to only last several months...despite how well I clean and prep the area.
