hey guys, i just got a pair of velocity deep vs with machined sidewalls, they are used and have some scratches, nothing real deep though. I was wondering, i would like to powder coat these to a custom color but what should i do to have these appear to be non-machined when finished? i figure that i should smooth out the side walls so they are less "ribbed" or what? sand them alittle? any one have any ideas or ever done this before?
