What type of primer are you using, a catalyst-activated type, or lacquer based? A light ''dusting coat'' initially is good all over, regardless of type of primer. After the initial coat ''flashes off'' or slighty skins over(lightly dries), go back with a light to medium coat and insure you have good coverage. After this coat sets up (and well within the recoat time advised in the product literature) go back over the part with your final coat or coats to ensure the gloss or texture you are looking for is obtained. This technique works well with enamels and urethanes, lacquers and 2 part primers. Remember that a fast speed (low temperature)thinner or reducer is easier to control the final results with by mix ratio or spray technique than a slow speed ( high temperature) reducer or thinner. Stay away from retarders unless you have a pretty good amount of experience with auto paints. Spinning the wheel is an excellent way to ease reaching the tight spots, but also a perfectly acceptable technique is to spray the face of the hub and rim and spokes, then walk around the wheel while spraying the edges of the hub and rim. Then shoot all the spoke sides from one direction then turn yourself around and spray them from the other direction. Then turn the wheel and do the opposite side. Do the backside first, and set the wheel on the hub back and do the front. Another way to help yourself is to adjust the gun volume before or while you spray. If your trigger bottoms out when you pull it back, chances are the gun is throwing too much paint to control in crowded and curved areas of the wheel. Adjust the lower knob on the back of the gun clockwise. This will prevent too much paint while you are busy looking for how much coverage you are getting.
