I've been asked several times where I had my wheels powdercoated, and because I bought the car with them, I didn't know. However, as most know, I recently hit a curb - quite hard. I bought a new wheel, and had a place called Powdercoating Systems, Inc. do their work. It's $92/wheel, or about $313 for all 4. They did a great job, and didn't take very long.
Just recommending them to anyone interested in the South Puget Sound area!
Oh, and they are located just off of I-5 and I-705 near Port of Tacoma.

I know nobody in the South Sound region will see this, but if someone ever needs it, hopefully it will show up on a search result.
