That being said it sure makes an attractive finish.

What you have experienced is the result of poorly applied powder. Most likely from a place that caters to the commercial side more so than to the custom side.
Scratched and rust starts? No different than painting. Exposed metals rust. That's what they do.

How does powder finishing hold moisture against the metal? Do you realize the powder is baked at around 350° to 375°?
Commercial coating is down and dirty to make it pretty.
Powder finishing done properly requires very good prep work, the application of a powdered primer and then the finish powder application.
Similar to painting, there's more to it than simply spraying and praying.
