Well that was a real bummer
I see lots of views but no response. Anyway, many thanks to everyone that took a look at this thread.
In the hopes of providing more information to everyone that has a similar interest, I called a place that does both Hot Coating and Powder coating. It appears that there is
no choice on car rims. The only process that can be used is powder coating. One of the secondary operations of Hot Coating is polishing to get the high luster. That is done in a tumbler (usually a revolving barrel with various media that is changed depending on the effect or the surface finish). Tumbling works well for manifolds, headers and just about everything
except for car rims. Car rims have a denency to not polish well and they rotate inside the tumbler on their rims instead of tumbling. Because of that the hot-coat chips or flakes off of the rim edge and produces a poor finish.
I guess I will consider a powder coat finish. I have found a wide range in quality among powder coat providers. The biggest problem is "orange peel". Some think it is beautiful (a poor excuse for lack of heat control or oven timing). The search goes on.
If you have a different view of what I found out please share that information. TIA
