So it recently rained a bit (oddly enough), and my rear brake drums got rust spots. The car is always garaged and that day it happened to not be. The drums are painted the usual black (opaque,flat). Thanks in advance.

Application of the vehicles brake system will remove the rust from the rotors by friction (if it really bothers you replace the existing rotors with zinc rotors (zero rust)
What gets overlooked too often is that one must be a student before becoming a teacher.
Rear drums, how old of vehicle?
That rust is normal by the way, unless they have been media blasted after buying the car to remove the factory paint, and a good high temp paint used for calipers is applied.

I sanded them, cleaned, degreased and painted with BBQ paint.
These pics are from 4 years ago. After 2 years, rust started to form at the edges. They havent gotten much worse since then. They are still black.
Im sure they will last much longer if done correctly... What Ron Ketcham said.
Before
After
It appears they have held up well.
The high temp caliper paint has a more robust resin system than the BBQ paint, and it will last longer, especially when one takes the correct preparations steps as you did.
I have found that three coats, first thin, second medium, allowing some cure/dry time between coats and the last coat as a filler and gloss, produces what appears to work the best.

That AFTER picture is from 4 years ago, as well.
I can take a picture of them if you want, so you can see what they look like now.

Let`s get things on track.
Are you wanting to know about "drums", "rotors" or "calipers"?
First post was regarding drums, and now you are saying zinc rotors.

If they get worse im going to have to do the same.

Just that I was telling TOGWT, that they were in fact the rear drums.
On *MILDLY* rusted rear drums, where the oe finish was still basically OK and there was just a little light rust in some places, I did OK by polishing with KAIO and then with BlackFire`s Gloss Enhancing Polish. I topped the BF GEP with BF sealant and it worked out surprisingly well. So well that the BF-stuff approach is how I generally handle mildly compromised matte/satin/flat black bits.
If you wanna redo `em right, the best "rust treatment" stuff I`ve found is Rust Bullet`s Metal Blast, works a lot better than other Rust Dissolvers/ "Navel Jelly"/etc. Use that stuff and then apply your paint. Or just use it to clean up the rust and then LSP things; I used it on the S8`s rear rotor hats (light surface rust breaking through the OE silver paint) and then just KAIO/FK1000Ped them, and it held up fine for nearly a year...OK approach if you don`t mind redoing it every now and then.
They still make cars with drum brakes?

When I was car shopping with my daughter for her 1st "new" car last week I realized many of the the lower trim level vehicles we were looking a had rear drums....the was enough for me to insist we go up a level since I loathe working on drums.
