Thanks. This morning I took the housing over down to OzHemi's place and we pressure washed it to get all the grease and grime off. After that I brought it back home, made a trip to Home Depot, rubbed it with a fine steel pad and some mineral spirits, and shot a couple coats of primer over it. It's just a light coat for now to prevent rust. I'll clean it up, sand it, touch it up, and paint it when I get the housing and diff back.
