Pitted metal in roof

[markeb01]

Yes, in fact I used the same stuff on the top of my rear fenders. After 10 years on a gravel road the tops were littered with star chips. Rather than completely stripping to bare metal, I thoroughly feather edged all the chips, which left the surface clean but wavy. I rolled on the primer, let it cure, blocked it out and shot on the finish paint. Even when wet the fenders shine perfectly smooth. This stuff goes on thick and doesn't shrink, so it doesn't cause any problems later on. If you've got deep pits it's always imperative to get all the rust and crud out. If I had rusty pits I would scrub them with metal prep first to neutralize any rust before priming.
