Yes, their website refers to it. They recommend thinning it with denatured alchohol about 5%. We worked with 3 gallon kits, due to the speed/gpm of the sprayer, and simply switched mixed pails as we went to keep it from setting up in the hose. Cleaning is a pain in the #$S. You have to break down the entire machine to make sure all the filters get clean as well as 50' of hose. There is an "autoclean" unit on this model and it works very well. Just make sure you remove the filters from the unit and the spray gun before cleaning. Just soak the filters in a small container of denatured alchohol. Xylene is also recommended as a cleaning agent, but we found that as it cleans, it quickly gets tacky from the epoxy. The alchohol stays relatively clean and IMO does a much better job for this material.
