I was practacing yesterday I noticed my airbrush is quite inconsistant. I noticed that when i pulled the trigger back a small ammount no paint came out, so i assumed i that i needed to pull it back further and i did and i got paint flow. but at times when i was trying to do thin lines and pulled back a small ammount paint would flow. so its kind of a guessing game as to weather or not paint will flow when i pull the trigger back a small ammount. i took the cap off and made sure there was no tip dry and there wasnt. i was using createx thinned with water. could it be that im not thinning the paint or maybe its just that i dont know my brush well enough ?
