NGC - Need a conductive adhesive...

...that will cure in low temps to re-bond the electrical clip to my car rear-window defroster grid.

Permatex (I think) makes an epoxy for just this application, but it needs 50-70 deg temps to cure properly, and I ain't got that in my garage now:

Has anyone used a different conductive adhesive that might cure at a lower temp? I have to ask before rigging up a hair-dryer to blow on the area for a couple of days.

Thanks,

I have a conductive paint, that dries like any normal lacquer. I have one that is copper filled, and one that is nickel filled. You can use them to repair damaged spots in the grid, but I would not call them adhesives.

I would use an extension cord, hair drier, and that epoxy.

A propane tank-top heater would cut that time down considerably.

I have this among my soldering tools:

Says 5 hour cure at 77F. 
Surely you can set a small, thermostatically controlled electric heater inside the car to keep the interior around 70.  Experiment with that for a day or so until you can acquire the adhesive.

Why not just redneck it on with ductape ?

How long to cure?  You could start the car with the heater running.

Ok, so it sounds like I need to solve my previous post about a garage heater first. And that idea about duct tape has me thinking....it might work with some of that aircraft 600-mph tape I have and a new connector that Amazon sells...

SilverSolder and a small butane torch. Pain in the ass to hold the tab against the glass with long needle nose, torch and solder at the same time, but when you get it, it's good.
  I've never had any luck with the permetex product.

On a sunny day you can easily get 70º. Warm it up faster with the heat on and then park it in the sun.

I have soldered the rear glass with a gun and good prep. No problem
