I used to work for an aftermarket bumper manufacturer. We used powder coat on the products, but touched up with paint, mostly Rustoleum.
Scrape any loose flakes away. Sand the bare/rusted area and feather into the powder coat. Paint the sanded are with high build primer, then sand it smooth with the surrounding coating. This is easy, and you wont need to do it to anywhere near the level of detail that you would if you were painting a body panel. Next, you don't need to prime the power coat, as it will already serve as a primer, but for best results, prime the entire bumper. After you prime, wet the bumper and use an extra fine, wet 3M pad all over it. Then rinse again, let it dry, use compressed air to blow it off. As stated above, the Rustoleum bed liner paint makes for a great, textured, easy to touch up or repair, finish. If you don't want texture, use regular Rustoleum.
If you want to use a base coat/clear coat automotive paint, you will need to wet sand it to a finer finish, then use a tack cloth prior to painting. A paint booth and HVLP paint gun would be highly recommended.
