Thanks Rail!
To quote our fine friend:
...Find a local powder coating company - I used Andrews Powder Coating, Inc in Chatsworth, CA which is close (enough) to where I live -- their number is (818) 700-1030 and I dealt with the owner, Scott. (
www.powdercoater.com).
Because the original side steps are already powder coated, they have to chemically strip them first, and if you pick the same colour I did, then they also have to add a clear coat.
Total cost of the powder coating was $311.00 (plus the cost of the side steps).
If you get a group together, you'll be able to "dramatically reduce the cost" - Scott's words.
I can call Scott and see what opportunities might exist...if you're interested, please post a reply!
