Since only solid-color powder coating is available, you'll likely have to sand the aluminum back down to get rid of the color on the outside.

I've had pretty good luck just hitting my pieces with black spray paint and wiping it with an acetone rag while wet. It's not PC, but it's an area that doesn't get directly handled, so it should hold up fine.

to do it in PC you would coat the entire part, then for the best finish turn(lathe) the part shaving off the PC were not wanted.

This is the way I would have said

How would sanding off the powder outside the grooves affect the appearance of the metal surface as opposed to a fresh, unpowdered piece? Is there a best technique for sanding the powder off?

Slow and steady. Depending on the finish you want on the exposed metal, you may need to polish it a bit afterwards.

I would also use something that has a bit of a 'stiff' backing to the sandpaper... (ie a block or something)

to keep things level and consistent where it 'sands'. fingers may add dips or wander from/into grooves..etc

It's a powder

Before it goes in the oven to be cured, you simply wipe off the areas u don't want coated off with your finger.

(I own a powder coat shop)

Yes but most probably were relying on the service from the shop, so it would be already fully baked.

Why would you not just mask them to begin with?

This is where Cerakote really outshines PC. You can do machine threads and it actually makes them much nicer than raw aluminum. No galling or sticking. No need to mask parts off.
