Are you speaking of powder coating your wood shells? Not sure if that's possible due to the electrical charge necessary for the powder coating process. If you are speaking of hardware, that's everywhere.

Sorry I meant to say powder coated hardware. (i.e. lugs, tension rods)

Powder coating is a very simple process. There are many many companies other than music based that do this. Set a charge on the metal, blow on the powder, and then cook it. That's it. Check around your area. Motorcycle and auto joints do this often. It's very cheap to do and you get to choose from a seriously large list of colors. It usually comes out cheaper with these guys than if you find some specialty music dealer online.

Thanks!!!!
