I have a Chevelle I'm working on, and I bought a Goodmark cowl hood for it which I haven't installed yet. I was just wondering if there would be any harm in putting it on unpainted? It has the black etched finish on it, not sure if that has any protection or not. It will be awhile before I get around to getting the car painted. Is it best to leave it off and in storage? Thought someone here would chime in.
