Yeah, I did a set of my truck wheels flat black using the Dupont wheel paint and they came out with a slightly textured flat black finish. I forget the brand I used for these, but they came out with more of a smooth satin finish, but also painted them in 95+ degree humid heat. So that may have played a part in it. Although, I think the finish actually suits the bike well. If you powder coat the wheels make sure you take it somewhere that has done many sets. You don't want any material in the bearing journals/hubs for obvious reasons. Also, if they bake the wheels at too high of a temperature it can effect the integrity of the wheels, weakening the metal. Painting can have a great durable finish, but it's all about the prep! Sand, sand, sand (320 grit and then 3M pad), degrease/clean, self etching primer, then about 3 coats of paint.
