Generally accepted by whom? The Powder Coating Institute, a national
trade organization for the Powder Coating industry doesn't seem exclude
urethane based or ceramic components. Since Eastwood bills itself as
providing "unique automotive tools and supplies, as well as expert
advice and solutions, for the classic car and hot rod enthusiast" I
would expect the enthusiasts that hang out there and utilize Eastwood's
"DIY" home shop equipment would be more limited in their capabilities.
It is of interest that Eastwood quotes PCI as well. PCI technical briefs
cover powders that flow and or cure at 250F to over 1000F, as well as
those that are UV cured. I think maybe your definition is too narrow.
The fact that multiple definitions may exist just highlights the need to
verify the process and the shop in question before making any
decisions.
