im assuming its just a case of rubbing down repainting and lacquering
remember this..... the finish will only be as good as your preparation. Imo u can get a really good finish out of a can. Use a good quality primer or build primer (etch primer is good on wheels), base and clear. Lightly de-nib between coats. Spray em facing upwards so its easy to get to the whole wheel. Also i have found it easier to let a little wind out of the tyres so the masking tape goes under the rim easier, oh and degrease the tyres.. makes the masking tape stick better.
