Yes, Tri-City Plating in TN does great work - I know a lot of people that have used them and I've never heard of anyone having any complaints.
Located very close to VA-NC-TN border and also Bristol NHRA/NASCAR track.

Tri-City Plating

I drove down there and dropped off the front bumper on my 70 RR about 11 years ago - they plated it and shipped it back to me.
Price back then was around $300.
Bumper still looks great.

Prices have gone up a bit since then (see price quote page on website), but still a great bargain.
