And that's why I hate airbrushes … This afternoon, everything went fine, so tonight I put in the 0.3 mm needle and some AMMO/Mig airbrush-ready paint. After a little bit of test spraying on a piece of kitchen roll, very soon nothing at all came out anymore, A bit of fiddling later and it started blowing bubbles in the paint cup. What followed was almost fifteen minutes of messing around with the airbrush (trying to spray, pour out the paint, put water in, disassemble bits, blow things through, wipe it clean, reassemble, put in paint, go back to the start of this bit in brackets) and it worked again. Good! So I took the model to hand and started spraying a little test patch on the underside, to see if the colour was right … Except that no paint came out anymore again …
Bastard thing! Ten minutes into the ultrasonic cleaner with it. That did it, afterward it sprayed water just fine again. Put some paint back in, and what do you think? Exactly: it clogged up immediately. It didn't want to spray any paint anymore, soon started blowing bubbles in the paint cup again, etc. Another ten minutes in the ultrasonic cleaner, and then back into the box — I've had it with this lark for today.
This with two different bottles of airbrush-ready from two manufacturers, BTW. I think I'll need to try this same paint in my Iwata to see if it does work in that (it always has, though), and also try totally different paint in this cheap airbrush. But not tonight.
