Attaching Side View Mirror Glass
I have done a search on this and it seems that most people resolved this issue by purchasing a used mirror assembly.
My side view mirror glass fell out. I just purchased replacment side view mirror glass from our host. I have an '87 with heated mirrors and I'm looking for a good adhesive to attach the glass to the plastic backing plate. Has anyone used epoxy or JB Weld (or other) and can confirm that this will work with heated mirrors? I really don't want to be the guinea pig with mirror glass being $50 a pop. Thanks!

I have replaced the mirror glass on my rectangular stainelss side mirror with black RTV silicon and it has held fine.
I replaced the mirror glass in my old 944 which was a flag mirror like yours, but it was not heated....so not sure if it would work for you. On the flag mirror I used Liquid Nails Heavy Duty Construction Adhesive. Comes in both a squeeze tube and caulking gun style tube. That stuff is unbelieveably strong. It is NOT the crappy basic stuff they make for old fashioned 1/8" cheapo "wood" paneling. Again, not sure how it would work with the heat, but I'd be surprised if the heat was hot enough to do anything to it.

Epoxy will not be a good idea. Will not hold well to plastic and is too brittle when cured. You need the flex of a proper adhesive. Go to an aout glass shop and get them to put some auto mirror adhesive on the mirror. Probally will cost 3-5 bucks. You can also buy a tube for around 10 bucks.
Good luck, Ben

Ben, I agree with your advice, but just for the sake of clarity, neither the RTV nor the Liquid Nails Heavy Duty Construction Adhesive I recommended is an epoxy.

Dan, I didn't read your post before responding. I also believe the liquid nails would work because it keeps it's "flex". The heat would not be a problem because it doesn't get that hot. As a matter of fact, I believe Liquid Nails makes the mirror adhesive I am speaking of.

I called a local glass shop and they said they have a liquid mirror adhesive and a thin double-sided tape available. Thanks for the resolution.

I may be totally off the mark here but if I read correctly you have an 87 with heated mirrors. Unless they have been replaced 87 Carrera's have power flag side mirrors and you stated heated glass. You are going with the factory rreplacement and not trying to glue on a piece of plain mirror. The OEM mirror glass is an assembly with the glass already glued to the backing plate. All you would have to do is remove you old backing plate and replace it with the new glass/backing plate assembly.

When my mirror had fallen off, I purchased from our host the replacement glass for $60 IIRC and it came already attached to the backing plate...All you need is a long skinny flathead screw driver to replace the mirror w/.
I also wrestled w/the idea of glueing a mirror to the existing backing...but in the long run it was much simpler to just buy the mirror and install.

I guess I should have waited until the part showed up. It is already mounted to the plastic. I did call Pelican about this issue, but they didn't indicate that the mirror was already on the backing. Thanks for the help!

Maybe a little late to this game, but I used 3M heavy-duty double-stick tape to put mine back on...

Does (doesn't) this tape raise the mirror height making raised around the edges?

I know this is an old post, here is my attempt at re-attaching the mirror on my 98' Boxster.
Basically cleaned both the mirror and the housing with Lift Off goo remover, then used some GE silicone glue. Holding solid. I think key was cleaning the sticky goo off and using the silicone glue. Here are some pics... Porsche Mirror Glass Install | GTSparkplugs HTH Sandy

My attachment using just silicone glue has lasted some 10 years...
