For machinery and implements you need an oil based paint, not a latex. The latex paint would be perfectly fine painting metal on a house, like black iron pipe gas lines, ect… but those aren’t subject to abrasion while being used. Oil based enamel like Rustoleum is best for the OP’s use.

I wouldn't be bit surprised if it comes with at least a light coat of industrial primer. I've seen a lot of gearboxes at work for heavy equipment, and on the farm come this way. And usually pretty clean on the outside as far as oil residue.

But if it does come bare metal and a slight bit of flash rust, a light coat of Ospho Ospho Rust Treatment - Since 1947 will solve that problem. I've been using it now for about 10 years on my old tractors on rusted fenders, rims, etc. Even used it on an old shed roof last summer that had a light rust on it, then top coated with an asphalt sealer. It kills rust, and also etches metal to prepare for painting. Just need to let it dry for 24 hrs before top coating.

What I've used it on so far has worked well. No rust bleed through like before with just cleaning and using a rust proof primer. I'd advise just getting a quart as it goes a very long way. It is as thin as water. Ace Hardware handles it locally here and honestly has the best price. Open the link above and select "Directions for use". Do note is is a phosphoric acid, so care needs to be taken when using it.

Just paint it whatever color turns you on!

I use black on my junk.

Prep the area with Lacquer thinner, before painting.
I have been using this method for 55 yrs.
