Believe it or not, J-B Weld makes quite a few different products above and beyond their classic “J-B Weld” metal-filled epoxy — like this stuff designed to re-attach rear-view mirrors.

I came across this because one of the project cars that’s been gracing (read: pissing fluid all over, getting pushed around it, and generally frustrating everyone who visits) the Toolmonger shop came to us with the rear-view mirror sitting in the passenger seat.  Seriously, this looks like just the ticket.

It’s a two-part cement.  The adhesive itself comes in a snip-top packet, so you just snip the top and apply it to the mirror bracket.  You apply the accelerator — which comes in a felt-tip applicator — to the spot on the glass where you’re going to stick the bracket, wait 30 seconds, and put the two together.  Thirty minutes later it’s completely cured and you can re-attach the mirror.

Best of all: it sells for around $2 from a variety of vendors.  We found it for $1.69 on Amazon.

    Hmm.. Wouldn’t you also need to put accelerator on the surface of the bracket before you put the adhesive on it?

    Rick: They mix when you put ’em together — that’s the way it’s designed to work.

    This stuff works well. I’ve tried using sticky pads designed for the job before, but firstly, they are really, really hard to line up (you only get one chance) and they fall off in 6 months. Mirror Weld actually seemed to work, through hot and cold, as well as it being possible to slightly move the mirror to align it.

    Piece of advice – line the mirror up first, and get someone to draw an outline with a thin black marker on the outside of the window. Then when it comes to putting it on with glue, you get it right first time.

    Trying to figure out the difference between this and the commonplace Permatex cement? Set me straight.
