Keep in mind, one could swap the big pot for the stock, one quart pot so there was less clean up and waste.

Using the above (adding pressure to the remote pot), I suspect even many a three stage could play with latex paints.

Pottzy, look into the Cricket siphon sprayers. They are more than just gimmicks and actually get the job done. And, because they use common canning jars, you can store and swap between paints.
