The DTM line of disposable paint gun cups combines all the steps of paint preparation into one easy system. Simply insert the liner into our hard cup to mix and measure, snap the filter lid on the cup, thread the collar on the hard cup, and you are ready to spray. The closed system allows you to spray with the gun at any angle, even upside down. Cleanup is easy: detach from the gun and throw away the lid and liner, or seal the lid with the stopper for later use.
