ThanksSpraying a coat of primer, then a topcoat would be just fine. All it needs it to be sealed off from the elements. Using acid etch primer would be even better. You can get that in a spray can, online or at an autoparts store.
ThanksBe sure the primer is compatible with the paint. Try to use the same brand. I know Rustolium wasn't known to like several other brands. I think I read some time ago they reformulated their products to be more compatible, but try to always stick with the same brand for best results.
ThanksIf you really want it durable and sealed will, use a 2 part primer.
I've had good results on other items with 2k spray can epoxy primers. Seems expensive for a spray can, but you're getting a 2k primer job without the setup or cleanup. Great for small jobs like this.
Knock off the loose material with a wire brush or a sander and paint with POR15... It is made specifically for that. It catslyzes the rust and seals it permanently.
