John,

Thanks for the heads up on powder coating uses, and to consider the properties of the materials being used (compatibility), very important.

For me, use an industrial company that is local for the different coatings used. Stay within one system, do not mix and match systems, and use recommendations of their knowledgeable professionals. They know their state of the art materials. I am a totally one system/process person, again no mixing of different systems. Lucky that this industrial company, is owned and managed by car guys, and are friends with them. Also, find the properties of these newer materials of interest to me, like the speciality epoxies, ceramics.
Some of the materials comparable with specified epoxy powder coat, are newer from Germany. Some of it is expensive too.
Again, I let professional knowledgeable of materials choose products to use, along with history of success.
