black powdercoat for rims
a two step (base clear) paintjob will come out shiner than powdercoat anyways. in my sig the 10 spokes are semi gloss black powdercoat, and the black 5 spoke wheels are base/clear check it out
as for price wise, depends on how intricate your wheels are and if they would need to be sandblasted before being coated. ive done them for $50 a wheel if i dont have to sandblast them
