Thanks - actually looking at this place:
CLASSIC POWDERCOATING - GAITHERSBURG, MD - POWDER COATING ANYTHING METAL, ANY COLOR
...because it's about 5 miles from where I live which is ideal. Leery because I don't know anyone who has used them but I sent them a request for a quote and am interested to see their response.
Thepowdercoater.com is still my first choice but I have a show coming up on 8/11 and I'd be cutting it really close if I waited until I pick the car up on the 30th.
