I do not recommend this product. Despite careful surface preparation and application exactly as described in the product directions the rearview mirror fell off again after less than a month in my vehicle that sits out in the heat of the sun.I have used products like this before without issue over the years and they used to last at least 2-3 years, but as of last year I have found that every variety of these single-use rearview mirror adhesive kits have failed to provide a lasting bond. Add to the poor results the single-use nature of this product and you have another reason it is not a good value.Thanks to helpful reviews by others I was put onto a superior product for attaching my rearview mirror also made by Permatex. I recommend Permatex 84101 PermaPoxy sold right here on Amazon. Application is simple and the rearview mirror is still firmly in place over 6 months later.
