Mirror separating from heating pad
 

My side mirror (left side, I mean, the correct side :D) started shaking a bit. It was increasing over a short period of time.
I pulled the glass out just to find out everything is solid, except the glass started separating from the heating mat.

Any suggestion how to glue it back?

Did google just give me the answer?

Loctite Super Glue Glass.

Other suggestions?

I thought about polyurethane, but since it is heated the temperature changes may mess it up, plus adding extra layer is not a good idea.
