Maybe a silly question but....
Can you powder coat aluminum?
I'm thinking of radiator shroud..

Cast aluminum may require a pre heat to get any outgassing out of the way. Extruded stuff typically does not require this. The casting process can create small air pockets in the finished product, which heat up and 'out gas' during the heating process. The result is little spots that look almost like dirt in the finished coating. Really porous castings can outgas bad enough to leave bare aluminum showing. Old cast iron stuff is really prone to outgassing. If you really want to get your local coater excited, tell them you want to bring in a bunch of old house radiators to be powder coated, or better yet, an old cast iron bed frame. How do I know this......I was told by a powdercoater that aluminum needs a bake cycle before it's coated.
Don't know if that's true, but worth asking about.
I've had 2 sets of wheels powdercoated - 1 set of steelies, and a set of aluminum OEM wheels - and won't do that again.
The steelies have rusted, and the aluminum ones would mar & scratch very easily.
I have wheels I painted 30 years ago that still look new.
