Review on 🎨 High-Quality MPS Disposable Paint Spray Gun Cup Liners and Lid System, 50 Pack - Mini Size 6 Ounce (180ml) Kit - Includes 50 Cup Liners, 50 Strainer Lids, 1 Durable Cup with Retainer Ring, and 20 Plugs by Steve Brethorst

I've been using the 3M PPS Cup System since 2014 with my Fuji Q4/XPS and T Series Turbine Guns and HVLP Multi Compressor Guns with adapters. These versions of Master Paint cups/inserts and lids work exactly the same. There have never been any leaks in this system or in the PPS system. They offer significant savings over PPS, which is great. When making water based products I usually reuse liners and lids at least once as they are easy to clean with hot water. I am getting rid of liners and caps when spraying solvent materials, albeit after multiple spraying sessions of the same product over a 1-2 day period. I wouldn't hesitate to continue buying these to save money compared to PPS branded products. I find the 6 ounce and 20 ounce cup sizes the most practical. Increasing the size to 28 ounces increases the gravity weapon's weight and can slow maneuvering on all but flat objects.
