Yes the ideal paint gun to paint steel wheels is the magic painter gun. The magic painter gun is a gun that does not use compressed air and saves upto 60% paint. The special feature of this gun apart from the paint savings is its penetration capability to reach into grooves and crevices of the wheel which otherwise cannot be reached by electrostatic guns because of Faraday cage effect due to consistent grounding is required. Also paint resistivity has to be maintained. The cost of maintaining electrostatic guns are also very expensive and there is a risk of operator safety. With the magic painter gun no such earthing or grounding is required and it can penetrate to all the grooves and crevices of the wheel. We have supplied to wheel companies worldwide and they are successful in saving huge amounts of paint and money. The magic painter gun gives a transfer efficiency between 85-90%.
