Do not powder coat it. Send it all to Shaun at Tru-6, don't fret the cost, what ever it is, it's totally worth it. He has my entire intake system, velocity stacks, throttle bodies, injection lines, linkage, trailing arms, brake calipers, brake dust covers and he's fixin' to get my entire front end. I'm sending this stuff from Denver. The State and Federal EPA's ran every single commercial plater out of Denver and there is no one I now who does Porsche OEM specs in-state. Did you see Shaun's site?

This is his work
