K:
As it turns out... I ordered a pair of these...and thay arrived at my works before crimbo...I only collected these after the holls though; so this is the reason for the delay in getting back (ong-bak?) (eh?)...sorry Im drunk again)
Anyway, I can confirm that te mats have a peel-away backing-paper that reveals a self adhesive side to the mats(the wire terminals are on the non-adhesive side ofcourse and are about 13mm from the edge). The glue seems good, and I reccon it will bond well if the rear of the mirror glass is properly clean and flat before sticking the mat on..... It also loooks like the heating strip is well-electrically insulated (at 12 volts) from the glue-layer too. (I was worried that the heater strip would short on the silver oxide or what ever it is on the rear of the mirror) ....so my only stress now, is the bonding of the mat-clad mirror-glass back onto the mirror mounting securely.
The mats are 12 Watts each so they should get fairly "George Michael" (Warm/Wham)....(bad joke)
...Have you ever touched a 10 Watt resistor with your finger...ouch!!(sizzle..smell of bacon)
The heating wire tracks pretty much cover the pad but there is about 3mm between the track so it would be possible to punch the mats between the wires to blob an array of epoxy dots or stripes......also The K10 mirrors are bigger than the mats so a separate pannel could be made to interface the bad-mirror assembly to the mounting...?
I was thinking of adding these to the rear window heater switch and may-be reviewing the fuse rating (I havent looked at this yet though)
I'll keep you updated but it might be a wile as I have quite a bit on at the mo
