Rustoleum spray-bomb should work fine. Use their metal primer first,

Surface prep is Critical.

Clean! No dirt. Minimize surface oxides.

Degreased! Use lots of paint thinner to eliminate
finger oil for example. Change application cloths
often so that you don't simply smear grease around.


I would scrub everything in lots of hot water and strong detergent, and
then wear rubber gloves afterward to protect the part from finger
grease. Solvent is nice as a last step, but it takes lots and lots of
it to remove large amounts of grease.
