I've done a fair bit of research in the UK and come up with nothing, so
cast myself humbly on the mercy of this group. ;-)

I've got an old car which has heated door mirrors. Both the elements are
burnt out, and spares are no longer available. The mirrors themselves (the
heating was an option) are no problem. So what I'd like to buy are
suitable heating mats to replace the originals. RS Components do silicone
heating mats for 12 volts, but not in a suitable size which is approx 100
x 50mm. The thickness should be not much more than about 1 mm.
The originals appeared rather like a PCB made of thin flexible plastic
with silver coloured tracks as the heating element.

I can make copper PCBs at home using conventional methods, and of course a
similar method using this plastic material would be great. If I knew what
it was and where to get it.

I'd also be willing to pay for a small production run of say 100 if the
price was right as other owners are in the same position and winter's
coming on...
