Clear coat or not

Picked up this aluminum intake for my son't Dart paid $50 for it and a local auto body shop blasted it for $50 so not bad for $100 total investment. My question for you guys is does anyone clear coat their aluminum manifold or leave them bare. It seems the factory finish on a new out of the box intake may have some sort of coating but can't say for sure. I'll do a little detail work on it before installing but just wanted to get your feedback. All of my blower motors are black powder coat for easy of cleaning and protection from the fuel alcohol just loves to eat away at aluminum so I even contemplated a satin clean coating.

Your thoughts are always appreciated 210305198_3775247222577084_2243532042544266843_n (2).jpg 20210713_104514.jpg
