I see alot of new people having problems with there airbrush with it spraying badly with the paint there using? So I hope this helps getting your paint to spray good, 1. Start with a clean (and I mean clean)airbrush. 2.strain the paint (a small peice of nylon stocking put under the lid works well) 3.Starting with reducer put 3 drops of it in the airbrush, then add 7 drops of your paint to the reducer and mix well! 4.Ajust the air pressure to 40 p.s.i. (not sure how many bars that is for the other side of the world.) 5.try a test spray and see how it sprays? If it won't spray add another drop or 2 of reducer or turn up the pressure ,test again?if it spider's lower your pressure till it sprays good 6.keep adjusting the paint or the pressure one or the other not both so you know what works then 7. Write it down so it gives you a starting point next time. 8.Next time you start painting start at the pressure and paint/reducer you wrote down! (Due to changes in the weather you might have to add/reduce pressure or paint/reducer) 8. Have fun asthats what its about!
