powder coating is a dry powder that is electrostaticly charged and sticks like a magnet. then is baked on. this forms a type of skin. this is more durable because it can be much thicker and be much more consistant
paint is a liquid that needs to be sprayed on. will be less consistant and is weaker.

Correct application process. But like you said it forms a skin, doesnt really bond to the metal.
Its thicker, like i mentioned so it can be allied over 80 grit/scratch surfaces and with enough powder will level out the surface and not show the imprefections. Paint needs 600 grit for color coat to give a glass like flat finish. Primer should be around 320-440 prior to laying it down, for physically adhesion
A good painter is consistant with the application. Look at a heavy metalic content or pearl base coat… if you suck at spraying it will look like bawls. powdercoat, aslong as it covers the surface 100% physics and chemestry do the rest.

Powdercoat wont bond to metal like a primer that will etch into the surface. If you chip the powdercoat (not that hard to do) moisture can work its way under the powdercoat and weaken the bond to the wheel.

Exactly. Not only water but chemicals, salt… but just like paint anything that gets under the surface and touches the metal… it is fucked. but yeah when PC chips, it will catch other rocks, stones, branches, what ever else comes in contact with it physically and can and will keep chipping.
Metal etch primer is the strongest chemical to metal bond I can think of like you said.
