Rear Window De-Misting
Posted 29 November 2012 - 08:48 AM
Can this be remedied?
Any suggestions welcomed

Some of the lines will have a break in them, where some of the paint has come away. This means the electricity cannot get through, and so these lines do not get warm.
The window is designed so that if some lines are broken, the rest still work
You can fix the problem by repairing those broken lines. Halfords sell a special paint for this, which has tiny metal particles in it so that it conducts electricity.
You may be able to get it cheaper, eBay for example.
You just need to re-paint the broken sections, so that the electricity can get through.
You don't need to do the full line, just the section that has worn away. This may be just an inch long.
Mask it very carefully with tape first, so that the new lines are no thicker than the existing lines

Looks like being difficcult detecting the breaks - have found three not more than a couple of mms long, and there are more somewhere - and this weather is not very conducive to that type of job

I can see a change in colour where the breaks are : the working section is a dark brown colour, the damaged section is more of an orange colour.
Maybe placing white paper the other side of the glass will help to make this colour change stand out more?
I suspect the window lines are applied with a two-layer process - a base layer (the orange line I can see in some sections) and a conductive layer on top of that (the brown line that's broken and missing in some areas?
Perhaps you can see the same colour change on your window?

Maplins do a similar product that's designed to make/fix circuit boards, which should work on your window. It's only small tube though, so mask up carefully so you don't waste it
