From all that I have heard about Imron in the past I think it is probably just as tough, if not more.
Dupont Imron is what we used to paint cabover Freightliner bodies back in the mid 70's. It stood up real well to road gravel and stones. The toxicity of Imron is probably one reason painters have to wear space suits today when they paint. We wore a dust mask, long sleeve shirts and jeans.
