Anyone have any pointers/tips on doing under body work? I am planning to start off with something easy - the front arches (under the liners) I know some of the paint has come off and i, plan to rub them down, primer, paint and waxoil them. Obviously it doesn't need to be that neat as they are never seen. I was just going to use wire brush attachments on a drill to remove suface rust, them primer, paint and so on. Is there a certain type of primer (anti rust stuff?) to use?

Any tips wold be great!
