My problem with powder coat, at least on my farm equipment, is that once it starts to rust underneath the plastic, and it will if used in the weather, it holds in moisture against the metal and before you know it you have sheets peeling off. With paint ... no problem, sand blast and repaint, with powder coat .... a blaster will charge you twice as much, that is IF he will even take the job.
With paint ... I take out the angle grinder with a sanding disk, take the rusted area to bare metal, touch it up, done.
I've gotten where I won't even buy a piece of equipment that is powder coated anymore. Great for consumer stuff I guess, but for heavy duty applications that get a lot of rough use, and a lot of weather, not so much.
Right now my log splitter is outside with all the powder peeling off, in the spring that will have to be blasted and refinished in paint.

If your powder is doing that then the surface wasn't prepped properly, or there is a serious error in how the powder is being applied & baked.

We coat farm equipment, chassis, industrial switch boxes, fences, earth-moving equipment down here and have zero flaking or rusting issues. And this stuff sits outside in our much more aggressive UV atmosphere than what you guys have in the USA.

Without a doubt there are differences in the quality of the powder applications. But since I'm not doing the coating ... I have no control over that. So I have to opt for what I can fix if it doesn't hold up well.

Bear in mind while our UV isn't as harsh as yours ... my stuff does go through temp extremes of -20 below zero F, up to 95 F every year. Well within the capabilities of the powder itself .. but the expansion and contraction cycles and the freeze / thaw cycles play heck with the substrate.
