I do mainly wood & wood veneers, so I use HPL and other materials needing CC sparingly. I tried a small pressure pot setup with the same results. Clean up was too time consuming and messy. Spraying was also a mess, even though I did it in the finishing room in the 12' paint booth.
We went to a self contained airless system (you buy pre filled tanks, similar in size to a 20lb BBQ propane tank), and a gun and hose - which gets attached and filled, and left until the tank is emptied then transferred to another tank.
With this setup you pay more for the glue, but the setup can be left pretty much indefinitely without issues. All I do is clean the nozzle with a toothbrush and some solvent and its good to go, each time, every time.
Also, the spray pattern (which is set via the nozzle you buy, much like an airless gun tip for paint) is very "clean", ie little to no glue shoots past the pattern. Easy to spray clean and without getting glue everywhere - and that is a huge plus when taking it to the job site.
