Powder Coat on 4130

Your definition of powdercoat is too broad. Its generally accepted that
powdercoat in the powdercoat community refers to a plastic like powder
that transforms into a solidly linked coat at temps between ~300-400F
(the coatings generally start flowing out at about 300F, but need to
cure at about 400). Urethanes and ceremic coatings are not considered
powdercoating.
Doing powdercoating at home is quite doable, but you need to but a
powdercoating gun and colors. You also need an electric oven you won't
be using for food. You can get these and read forums on powdercoating at
eastwoodco.com.
Powdercoating isn't just for looks. Like paint, it protects surfaces,
but as has been mentioned, its heavier than paint. Its stronger than
paint though.
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.
