I bought an iwata hpc .3m I've had problems with it not spraying paint. After about 3 minutes of airbrushing at about 30psi, paint wont come out when I pull back for paint. Immediately I think TIP DRY! So I wipe off the paint off the needle and try to spray but nothing comes out. I take it apart and clean it and it still doesnt spray liquid, just lots of air. If i put the tip very close like a few milimeters away from my skin or the paper then fluid will come out. but very little. even if i take the needle pulled back fully out of the tip so that my needle isnt controlling fluid then it still does the same thing no matter if i try to run paint, water, or cleaner through it. Last night I soaked the entire thing taken apart in a cleaner and water mixture cleaned the peices. still no luck. only sprays if its just about touching the surface or touching the surface.
