Use Solvent FlexLiner System with water, solvent and flammable based materials. Holds 32 oz of material. Includes 32 oz cage, liner, standard lid and plug. Good communication will fix most problems.
I would give Graco 1 star on the idea. This appears to be a fine product "for the portable sprayer it is built for", but I purchased for the Graco edge Plus HVLP which uses the same bag, they could have created a simpler model to work with the edge, but they didn't. I need somewhere to store finish not on the gun. I also need to get the finish off of the gun and fill another sleeve with water to clean out the gun. This works for me, I just think they could have come up with a system specific to the edge gun, similar to waht 3M has done.
