Was going to use these as the track set, but i think i like the look more than the black centers...I'd let the pics do the talking.
Things i learnt:
Make sure the wheel is bone dry.
Many thin coats.
Make sure to get the edge of the lip.
Steel wool after painting to get rid of the mist overspray.
Clean the spray nozzle or it will start to spattle.
Get 3 cans of paint, 2 was just enough. Would have been nice to have a spare for touch ups later.
I got this set fully polished, so i used the self etching primer just in case. Not sure if it is needed otherwise.
