Why Is the Needle So Inky?

As Dave mentioned many airbrushes wont even allow pulling from the front. I only pull the nozzle out of a brush under one of two circumstances..
1 its giving me trouble.
2 i just sprayed metallics through my brush, because they tend to collect and I like to make sure they all get out.

spray water / thinnner (if solvents) to get the bulk paint out of the cup and swab it with a cheap small paint brush And to be honest i dont even pull the needle out of the ones im using daily that often. if you dont let paint dry up in there its relatively painless to clean them out and keep them running. Admittedly i can be pretty hard on brushes... and the eclipse just shrugs my abuse off all the time.
