I've been flying airplanes a
I've been flying airplanes a very long time in Northern Canada where they do use chemicals to deice the runways, many of the airplanes I've flown are so old (30yrs +) the paint is missing in many many areas. And these things are fine... A 6yr old steel truck on the other hand is rotting out at the fenders and can corners... I think Ford was smart as hell to make an Aluminum truck. There are a ton of 2015s on the roads up here now and they all look fine to me.
