I give Commando valve covers a FULL factory-style restoration from start to finish, including the black wrinkle in a powder coating, plastic dip on the wire retainers, and the customer's choice of fully-polished or 2-tone aluminum fins. (They came both ways from the factory from what I've seen; most customers elect to have the original finish restored.)
I've done close to 35 sets of Commando valve covers over the years so you'll find LOTS of photo examples right here on FABO and on
my website Gallery if you'd like to check out the work. In fact, a set for member Mariner just went out a few days ago and should be on his doorstep Monday or Tuesday.
Feel free to send me a PM or give me call (if it won't kill your car project fund lol) if you have more questions or want to discuss particular details. I'm always happy to help when and where I can. :-D
