paint or undercoating

Either would work fine, so long as you rust-prep the brushed areas first.

Use a self-priming rust converter, or clean the areas real well and use a fish oil (or equivalent) rusty metal primer. Rustoleum makes 'em in their industrial enamels line.

The major drawback to the undercoating is drying time. It will dry to the touch overnight, but not be hard enough to endure any scraping for most of a week (unless you use a two-part... but then you're into big bucks)

So I have to use a primer? They sold a rusty metal primer.

What's that Lassie? You say that stryped fell down the old rec.crafts.metalworking mine and will die if we don't mount a rescue by Tue, 13 Jul 2010 07:49:03 -0700 (PDT):

See if you can find a source for a product called POR-15. You can apply it to rusty post wire brushed metal. Very strong, very hard coating. Moisture/rust cure. It can't take UV so you might have to put a topcoat on.

Personally I'd use neither. I'd grab some POR product like Chassis Saver and use it. It will seal in any crud you don't get cleaned off and stop the rust. It is really great stuff.

Someone made me aware of a product called Hammerite recently that sounds like it would suit your needs. I've never used it myself, but the comments on a message board were all favorable.
