The hardware for the Eastwood powdercoating system is not intimidating. Included in the kit is the power supply unit and the complete powdercoating gun. The power supply plugs into a 110V grounded power outlet, and has a trigger lead as well as a clipped lead to charge the part being coated. The electrical charge attracts the powder particles to the part being coated. Also pictured are bottles containing black and aluminum powder, which are the two colors we seem to use the most.
