Anybody ever polish an aluminum intake manifold?

I just finished Polishing my intake.. Many many, many hours.. let my rotary tool with sanding rolls do most of the hard work, then hours of hand sanding wet with 400 and 800 grit. Then I used felt ends on my rotary tool with Green and rouge polishing compound to bring out the chrome look.

It's not perfect and it's very hard to get into every nook and cranny, but every surface is smooth. should be easy to keep clean compared to the rough original aluminum surface. Did the same to my water pump and timing cover.

Check out the engine compartment / engine changes in my "10 year refresh" thread in members restorations.

It's still friggin winter here and My garage is not Heated.. Doing most of this polishing in the basement.
