Painting or Powdercoating Aerospoke wheels

Anyone got any advice on painting aerospoke wheels ?
ive had mine a couple of days now and they have started to chip.
I dont think white was the best choice of colour so i want to try and paint then black.

sell them and get some decent wheels. Or buy black ones.

what do you think is going to happen once the black chips?

and how have you chipped them - nothing should come in to contact with the rim / wheel!?
