Hard cups and collars support liners for the 3M™ PPS™ (Legacy) paint preparation system. 3M™ PPS™ is an all-in-one disposable solution for measuring, mixing, filtering, and spraying of paint materials. The system enables the painter the ability to consistently spray at 90° to the part, no matter the part orientation (even upside down). The all-in-one solution reduces the chance of outside contamination and reduces paint consumption.
