Stay BLACK. I am doing the samething as we speak. I am driving to the powdercoaters as soon as the FedEX guy gets here. I am going metallic black on all engine parts, plenum, valve covers, turbo shield, alternator, alt/turbo/intercooler brackets, and intercooler. I am going satin black on radiator top cover, powersteering bracket, and a few cover plates I made, but I am going with a silver that matches the seat color on all the tubing, like up-pipe, MAF pipe, solid rad hose, and jet hot on downpipe. Alt fan will be silver also. Then I replaced all the bolts with stainless. I'll post pics when done.
I hate polishing. If you want to polish, come on over and polish my 409.
Stay black
