I used a hi-temp, so-called engine enamel from the local O'Reilly Auto Parts. Color was white, same as the inside of the cowling, which is recommended by many to make drips easier to spot.

However, once I was done with the red RTV sealing up all the airleaks, the pristine white baffles were much besmirched.

Unless you're really into looks, leaving the baffles unpainted probably makes no difference in cooling performance and lifetime.

PPG single stage urethane paint over PPG epoxy primer. The same paint I use for the interior and panel (just different colors). Very durable. The baffles on the first plane look like the day they got painted 15 years ago.

Same 2-part Imron that I painted the plane's exterior. Still looks good after 2100 hours.

Default Flame Proof?

Do you have a concern in regard to fire resistance of the painted baffles? I was thinking of just going my my interior primer, Akzo 463-12-8. Not sure if it would be totally fire retardant. Wrote to Akzo. No response yet.

Baffle paint fire resistance would be #1053 on my list of 3 issues I'd worry about. If the fire is that bad, the cowl will be consumed long before the baffle paint.

Use a good primer and a good single stage top coat. The easiest way is to use the same paint and process as you will with the interior. Painted baffles is a simple thing to do and looks a lot better years down the road as compared to corroded bare aluminum.

Took mine to a powder coater. Right around $100 and they still look great.
