The mirror in the sunvisor on my 126 84 300SD is popping out. What glue do you recommend I use on this?

Contact Cement is one option (Not rubber cement) They sell this in Home Depot or Lowes

1. Make sure all surfaces are free of oil by cleaning them with something like alcohol.

2. Apply contact cement on both sides being VERY CAREFUL not to get any on the visible areas. (This stuff is very nasty to clean up, but dont worry if you get a little on the visible areas. You can clean it up by peeling it off with your fingers.)

3. Let dry (seperated) for about 15-20 minutes. You can test it with your fingers, if it is "sticky", it's still not ready. If you can touch the cement and it is not "sticky" to your fingers, then your ready to press both pieces back together and hold them for about 30 seconds.

The humidity has alot to do with how much you will wait until it's not "sticky".

Thanks,
Adiel

About the only thing wrong with the interior of my 83 when I bought it were the mirrors falling off. I used weatherstrip adhesive on them and they have held ever since. I just ran some masking tape over it to ensure that it'd stay in the right place.

Adiel said it perfectly for this project... but I would add for general knowledge ( from long years of using this stuff ) that one might want to test any foam which it was going to be used with in a small spot first.... it dissolves some.... but not the kind usually used with cars.... and that when planning a glue up try to choose parts which are going to go Straight onto each other... there is no provision for aligning this after they have been placed together... Looking at the picture you posted... and since contact cement is very strong... you might get a way with only using an inch by a half inch along the area where the vinyl meets vinyl along the edge... In other words you do not need to coat all the back of the mirror holder and the place it is going in order to hold it just fine...

Jeff, weatherstrip adhesive is contact cement...

It is a little bit different isn't it? Generally thicker than contact glue, sometimes quite pliable, takes a while longer to dry. I coated the whole backing of it, it isn't going to fall out.

I think the definition has to do with the way in which is it applied.. we buy it by the gallon.... but don't use it very fast ... so we also buy the solvent... it can be made as spreadable as you need... and on porous stuff you may want to use two light coats instead of one thick one...
But the idea is ... it sticks (best) TO ITSELF.... contact with itself is the criteria for its definition ( as far as I know )... as Contact cement.
And it may have been named primarily in relation to Rubber Cement.. which was developed for graphics and newspaper people so they could put something on, adjust it, and take it off if they needed to... without it messing up the paper....
So this is " IF you CONTACT it you will NOT be able to MOVE IT".... LOL
Ok,,, this type of glue is great... so in the ' more information than you ever wanted to know'.... if you have two large surfaces which flex that you need to put together then you start on one edge... and use waxed paper to keep them apart.. pulling it away while you compress them ( hopefully) where you want them.....
OK ! GO GLUE !!!

Thanks leathermang, I forgot to mention that fact...where a nice thin coat on each side is better than "big blobs" at sticking. The reason being, the "big blobs" can take longer to dry and then when you stick both sides together they might come off since it was not fully dry and leave one side with all the contact cement.

I think they originally used hot glue. That's what I used to reglue mine and so far so good. Either hot glue or contact cement will work.
