My father-in-law has a Piper Archer airplane, and like most of us here would do, I was eyeballing the paint when I went for a flight last weekend. The plane sits out in the weather 24/7 at the local airport. I'm pretty sure it doesn't have a clearcoat, and the paint is pretty oxidized/faded. Is there anything I can do to spruce it up, or is it toast because it doesn't have a clearcoat?
