Cleaning Shellac Spray Gun

I got several questions about properly cleaning a spray gun. I find shellac a bit more difficult to clean out of my gun relative to nitro and i spray such a small amount of shellac that i just use the prevail spray jars and keep an extra jar filled with straight dna to clean propellant tops when done. Ive sprayed about a gallon of target coatings water based topcoat over the last 6 months and of course it just disappears in water making cleanup extremely easyno brushing of small holes required just soak splash rinse.
