3M PPS Large Lids & Liners Kit:

3M PPS Large Kit contains 25 lids with micron filters, 25 liners (28oz), and 10 sealing plugs for use with the 3M Paint Preparation System. An all-in-one painting system that allows painters to mix/measure, filter, spray (in any direction!) and temporarily store coating materials. PPS disposable lids contain a welded-in filter which strains the paint material while spraying.
