I am taking apart my trailer to replace the wood bed. I took a wire
cup brush to the metal. I wanted to coat it before putting the treated
wood back on. WOuld spray undercoating or oil based rustomleum work
better?

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

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.
