Rear view mirror glue
 

I have used permatex twice on my rear view mirror. It has lasted about 3-4 years and then fallen off when accidentally bumped. Anyone use something that has lasted several years. I am using the original metal tab to the glass. Would a plastic one work better? What has worked best for others?

Visit a local auto glass installer. Have them glue it for you. Bet it wont cost much. Mine does not even charge for it

I used the Permatex as well. It just fell off again in the 100* heat we are having. The truck sits in the sun all day long. It lasted just a few months. I had the glass shop glue the one in my other truck. It's been a few years, but the truck is in the garage. They charged me $20.

Make sure you clean both the glass and the button really well before you install. I've had them not last long at all, and I've had them last for decades. I think it's just pure luck sometimes.

The glass people must get better stuff because I tried the permatex stuff cleaned and used the primer and it st still fell off
Our glass guy from work gave me some to use and its been 5+ years and holding good..

I cheated after finding a Spectrum rear view mirror at Pull-a-Part. The Spectrum looked like some kind of Chevy rebrand of a small foreign car. The car mirror was attached to the overhead roof which was a nice fit with the double wall roof on my 75. Bonus, the color was a match.

I tried super glue once and when it got knocked off it took a chunk of glass with it. There is such a thing as sticks too good.

Permatex extreme strength is what I tried this time around. My 79 sits in the direct sun all year long. I switch to a Saturn Vue rear view mirror that has temp and compass in the display. So this mirror might have a little more weight to it then a standard mirror. If this one falls off this time I will probably go to a automotive glass place and have a then do it. Although my current front windshied has a giant crack in the passenger side and two rock chips in it. I need to replace it sometime soon.

Prep makes a big difference.

I buy the button with the 3M tape and remove the tape so I have a nice clean new button to work with.
I buy the Permatex glue with the primer towelette.

• Don't try to glue it at lower than 75°F outdoor temps. I usually glue these at 9-10 AM so the glue is doing the early curing during the hot part of the day.
• Clean the glass and the new button with acetone then 91% isopropyl alcohol.
• Generously mask the mount area with some blue tape. Trace the mounting button with a pen and cut a windshield mounting button shape hole. Then remove the button shaped tape leaving the rest masked.
• Sand the mount area with 220 grit aluminum oxide sandpaper til it's obviously scratched and even a little cloudy.
• Sand the button.
• Remove the tape and clean the windshield & button again with Acetone & 91% IPA.
• Wipe the primer on the dry button and the entire sanded mounting area on the glass.
• Apply glue to the button.
• Press it in place on the prepped area and hold it for whatever time the package says to. I think it was a minute or two.
• Rip a long strip of painters tape and stick it on the not to be glued side of the button and the windshield to hold the button tight against the glass.
• Leave it taped down for at least 24 hours in the sun. I usually wait 48 hours or a little longer before mounting a mirror.
