Rearview Mirror Adhesive

I had wondered about the temperature being a factor, but don't find mention of it in any of the packaging instructions. It HAS been unusually cold and damp for Austin, Texas this winter. At least we're not shoveling snow! Something else I noticed while roughing up the back side of the button with 80 grit sandpaper is that the surface was not flat. I put the sandpaper on my workbench and took enough off so the entire surface was abraded - it's flat now! We're supposed to warm up a bit for a few days, so round three tomorrow.
