Vanilla Gorilla, I don't think so, from what I remember of my Air Force days, the canopy stayed clear as (seemed like an untouchable, unscratched glass). But the frame holding the canopy was clearly submitted to knocks and cracks, you would see the paint ripped off the rivets, them being shown in aluminium, when the frame was olive green. So, as long as the scale allows it, the canopy frame deserve some attention.
