new steering box

Good morning FABO, I just received my new PST 20:1 steering box.
Its going in my fresh paint Duster, I want everything under the hood to look really nice so my question to all of you is how can i keep this new steering box looking new?
prime and paint? clearcoat?...any product recommendation would be appreciated....
my OCD wont let me just install it without some type of coating, i love a clean engine bay...Rich
