If I put reducer in to my sbs cup and spray a little of that reducer so I can see it goes out of nozzle, and then let it sit for like an hour, I have reducer ''working'' exactly where I would need to clean my airbrush when I am done. Right? Yesterday I needed to go out so I put some reducer, sprayed a little and hour , two later I sprayed that reducer at 60 psi. After that I sprayed some water at 60 psi also. Usually i use dental brushes, but airbrush is working without a problem today. So colored red would be where reducer would soften color? Airbrush does pull the color or reducer from the cup, but when all the paths(chambers?) are filled with fluid, it just add from the cup to the fluid which is already in chambers? So In theory I have reducer sitting for an hour in all the parts which get in contact with color when I spray right?
