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 is not just for looks. Like paint, it protects surfaces,
but as has been mentioned, its heavier than paint. Its stronger than
paint though.
