While I don't very often telephone folks who submit finishing questions, this time I'm glad I did. When I asked a few questions, I quickly discovered that you didn't recognize the term "phosphating" or know anything about what the phosphating process involved. Likewise, you had never done any electrostatic spraying or know about any of the requirements for electrostatic application. Most surprising was the realization that neither you nor your husband had ever seen powder coating being done. I told you to visit a powder coating operation as soon as possible to get an idea of the scope of what was involved.
My next advice was to put on hold any plans to powder coat until you had a reasonably complete knowledge of what powder coating encompasses. I suggested you contact the Powder Coating Institute and visit its Web site, which you had already done. You wondered about attending powder coating classes, but I urged you to first read books on the subject. Then if you still felt it prudent for your shop to proceed on such a venture, a powder coating class would be a logical next step.
