I looked at a plane today which has a heated detachable de-ice plate which sits on the (outside!) of the windscreen. Unfortunately, the plate has at some point been left switched on for too long, and has caused a blemish, about the size of a 50p piece, on the perspex windscreen itself.
From the outside the spot simply looks "cloudy", but from the inside it has a "crazed" appearance.
Does anyone have any suggestions as to what can be done(short of a new windscreen) ?
Thanks,
FF
