## Questions & Answers

**Q: Can one mirror bracket be glued to a mirror bracket place on top?  Accidently glued the side that holds the mirror to the glass.**
A: It says you can glue another one on top of the one you already glued.

**Q: Do it work on aluminum button to windshield**
A: The button that I used was made out of steel, but aluminum will probably work too.

**Q: How do I Remove it?**
A: Remove the product or the mirror? The mirror slides onto a button and the button is what u glue to the windshield. To remove product, go to a parts store and ask em.

**Q: Can it be used while it’s cold outside?**
A: Yes. But you must heat the glass to the 60 degrees prior to application of the glue or it will not set. I had a heat gun, but I would imagine a hair dryer would work
