replacement mirror questions

We got the rugged tuff exactafit mirror for this. They say to remove all the broken glass.



But there's a heating coil behind it. And the mirror is on firmly.



Thoughts on putting the replacement mirror directly on the broken mirror? They give you 6 2" disks to adhere the new mirror to the existing backing. Even if the broken mirror pieces move different with temp, the disks are foam / there's a tiny amount of flexing they can do?

 

I guess you could try it but the foam may hold it too far away for the heat to work. They do sell replacement heated mirror glass. It has the same glass as the original. Advance Auto has a good selection.

 

badeyeben Thanks! Sorry, I wasn't even thinking of the heat actually working : )

But me being me, I'd remove the broken glass, damage the coil, someone turns on the heat and blow a fuse : )

At the same time - mounting the new mirror over the broken one - each piece reacts differently to the heating element / outside weather and shrink / expand as it's own piece vs. 1 large piece of mirror. And that pulls / pushes the new mirror on top of it and cracks the new mirror?

Like tectonic plates on earth - they move below and can cause cracks on the surface?!

The mirror pieces really aren't moving much at all I'd guess? I am just overthinking wayyyy too much!?
