Yes it will. And will probably peel off of heat from the breaks. Clear coat like was suggested by someone sounds nice, if it will stay on. If you look at cars in a car park, the places where clear coat peels are on the bonnet, roof, and trunk... Perhaps coat it with epoxy.

The best paint job I've ever seen was ordinary car paint with finely ground glass mixed into it. The glass has to be a powder. It eats through spray gun jets like nothing, but the final look is excelent. The guy that did it looked like his hands went through razor wire, so it helps if you can find good gloves! How about clear coat or clear epoxy with glass mixed into it? Epoxy will have a slightly yellowish look, and might go well with your orange body.
