well, I finally got this mirror fixed....

duct tape was starting to droop... with the heat and all... I called up a local auto glass place, went there, and the guy looked at it, and took a flat razor, and peeled the silicon off the back of the glass, but for the mirrored glaze square section, he had to use a flat chisel, the razor kept trying to cut the glazing.
Once he got that, he got out his handy, dandy tube of off-the-shelf silicone and proceeded to put it on the plastic mirror on the truck side... (there are 4 squiggly indents on this black plastic piece for the adhesive to grab to. and he put a dab in the middle. He took blue masking tape on the top/bottom, and said to be careful shutting the door, till tonite, and then tonite, I can take the tape off.
I asked him if this was a special silicone adhesive, he said no, just clear silicone you can get at your local hw store.
He was surprised my mirror was still in one piece, he said usually he has to order a new one from the dealer when he's done others. He said the previous silicone adhesive just dried out.
