The autophoretic process is special process marketed by a major chemical company. The equipment for the autophoretic at process can be manufactured by companies approved by the chemical company. Electrocoating is another means of coating truck and auto frames. In the USA the method used by most of the frame manufacturing companies is electrocoat. The equipment for this process can be manufactured by many companies.

In some speicality shops the preferred method of painting truck and car frames is powder coating. Equipment for powder coating is also available from many companies. I can not provide more process details in this forum.
