Correct paint color for a 1970 Dart 8 3/4 axle assembly

I'll let the fire rage. I'm thinking if a total sandblast, and a POR-15 semi gloss. My thanks to all. Paul.
POR15 peels off clean metal in time. Use epoxy on clean metal. Chassis Saver on Rust. POR15 is a thing of the past. It is good for an old rusted wheel barrow.
