hi Nicolas,
I had my moped (kreidler) powdercoated and wasn't happy about it. It wasn't smooth like the other parts that I painted in the same ral color. I would go for paint but that's my opinion. Maybe you can work something out with gold, would match your rims... just a thougt.

Sounds like you got a hold of a bad powder coater. With the ease of setting up a PC shop these days there are plenty of them out there. If you want to see some smooooth PCing check out the pan Deano showcased in HVWs early this year.
I agree with Zach. Get it straight before you take it too them. (Degrease it too.)
