Replacement safari door window heater

Years ago you used to be able to buy a stick-on rear window clearing heater matrix. You used to be able to stick it on like a phone screen protector then when you peel the top part away it left just the heater wires and 2mm wide sticky backed plastic bits, the only one I ever saw did work. Anybody seen anything like that recently? My rear window heater is goosed far too far to fix with the paint on metallic stuff so could do with being replaced.

To be honest it's probably it's just as cheap to replace the window at £48

Having just seen that one it is but they were quite cheap at one time..... Oh well looks like a new window then.
