I have that same gun, but I have not used it a couple of years. Do you keep several spray guns on hand in case you are doing several backing colors? I am pretty sure I was never shown the "proper" way to clean them when finished with them at the end of the day. What do you do in order to clean them and keep them unclogged?
I have two, but I might get a third later. I just got a melter for keeping everything warm so I’ll keep the alternates in there.
For each gun I pour any extra CB back into the bottle, and run through whatever is left that is in the pipe onto a random samples mold until it draws air from the cup. Then I use paper towel to get rid of as much CB as I can from the outer surfaces and inside the cup and lid. If I’ve still got more colors to do then the mostly-clean one will go back in the melter to keep warm and swap to a fresh one.
Once I’m done for the day I plug the gun back into the air, run the whole thing under hot water and spray the colored CB/water mix into the sink to clean out the CB path. Then I usually disassemble the pattern head to wipe that out, dry the whole thing with more paper towel. I usually don’t bother disconnecting the cup.
When I pour in fresh CB into a gun I spray a little onto paper towel to ensure that any of the old color (or drops of water from the cleaning) that stuck around doesn’t make it onto my target piece.
