I decided to powder coat the engine fan shroud. Actually, I used ceramic coating since it is thinner than powder coat.
I'm not finished yet but I've been working on polishing the fan. After I get it completely polished, I plan to dull it down with Scotch Brite Pad. I'm wanting to have a somewhat conservative look. I also will treat the polished fan with Gibbs to help preserve it a bit.
The shroud is coated in Cast Iron Gray Ceramic and has a frosted finish.
