I think you're the luckier one.

Aircraft canopies:

Mine are 1/600 scale, so except Heinkel 111, Focke Wulf 189 or B29 Superfortresses most areas of transparency are fairly small.
Advice at the time was to paint a pale blue (slightly darker on sides and undersides), then decide on the sun's direction and apply a tiny dot of white in that direction.

Vehicle windows:

GHQ suggested a gloss black then mark a horizon, with dark blue and paler hatching above this.

Closed cab  vehicles... I would use an 'off black' / VERY dark gray. Open top vehicles are a problem but maybe a light gray. Military kit usually dusty / dirty... so, if you can work out where the wipers would clear... dusting around the cleared patch 'can' work... but very difficult to do well... have tried and failed in larger scales!
