3M has designed a simple system called the Paint Preparation System (PPS) for easier, more reliable and more effective mixing and preparing of paint, primer, basecoats and clearcoats. And 3M now offers a 6-ounce mini cup system. The PPS consists of a hard cup with a collapsible liner and built-in strainer. The closed system means painters can mix, shake and spray with one cup and it helps eliminate leaks and drips. The system's disposable liner reduces the use of paint gun cleaning solvent and the need for hazardous materials disposal.
