So I've been modeling WWII aircraft for nearly 20 years and for nearly 20 years, I've come up with every reason I could think of, not to take on airbrushing. For what it's worth, I've gotten quite good at making rattle cans and gooey testors paint work for me. But finally after accepting the reality that you're quite limited in capabilties without an airbrush, I took the plunge and got one. Air compresser with tank made by Master that came with an airbrush. Enough for me, to start out.
First thing I'll say is that even with all the great advice, tutorials and guides, it's still like stepping into an abyss. You just don't know what you don't know; good or bad until you get one in hand and start trying it out. Having said that, as my wife can attest, I don't do anything unless I dive in, head first with the most half-***ed plan ever, that I've convinced myself is wholesale strategy.
This for once actually worked out in my favor. I was working on a B-17 until my 4 year old son and 2 year old daughter got their grubby hands on it and flung it across the room trying to make it fly. So what started as a model that had pain staking detail on the interior, turned into a very large painting mule for me. Here's where it got interesting.
First time out, everything went wrong. Got air, but no paint, clogging, erractic pulses of paint, splattering, more clogging, spills, you name it, it went wrong. It was so bad, I didn't even know what advice I needed, to try and get things sorted out. I convicned myself that my $20 airbursh was the culprit, didn't go all the way Iwata but went with the NEO for Iwata just to see if there was an actual difference. (Still waiting for it to arrive). In the meantime I figured, the one I have now, will be in the trash soon, so might as well stop being timid and just work out these issues, even if I end up just breaking it. So I took it a part...it came with extra needles and I remembered I changed them around thinking it might fix my problems. So then I realized between the .2 and .5 needles I may have mixed them up. Hard to tell just by eye balling it. So I did a process of elemination. I knew a .2 would "fit" everything sized at .5 but not the other way around. Sure enough, that whole time I had a .2 needle, going though a .5 fluid nozzle and a .5 nozzle cap....And didn't realize that Vallejo "Model Color" as opposed to Vallejo "Model Air" needs to be thinned down ALOT....especially when you're giving that thick paint all the room in the world to constantly clog a $20 airbrush, through mix-matched needles and caps.
That's when all the lightbulbs went off and finally had my a-ha moment. I put it back together the right way and BAM. Paint! Actual airbrush paint was finally coming out the way I saw it effortlessly do in numerous tutorial videos. From there, I taught myself how to thin paints, keep your nozzle from clogging, mixing, how to clean your needle when it's clogged and more. Once I had all that figured out, I finally got a chance to really start practing different techniques: pre shading, post shading, black shading, layering. Now I'm just obsessed with airbrushing the most random pieces of scrapped models I have lying around. The B-17 is now a faded very light intermediate blue, as it's my practice run for my CorsAir paint scheme.
Anyway, I learned a few things. First- I CAN'T BELEIVE I WAITED THIS LONG TO AIRBRUSH!! More importantly though, this business about cheap airbrushes vs. expensive ones. I think it's like anything. Your tools are only as good as your skill. I play guitar and I tell people all the time: A $2,000 Stratocaster is not going to make you all a sudden play like Jimi Hendrix. 2,000 hours of practice will get you on that road. I've read every bad review imaginable about this Master airbrush and after really, really working with it and learning the ins and outs of an airbrush, I honestly don't see what all the hate is about. Perhaps that's just me still being new and not knowing what I don't know, but when I get my NEO, I'll know more on what really counts between "cheap" and "expensive". Right now, I'm having way too much fun, shading and weathering random pieces of styrene wing halves.
So my advice to other NOOBs: Have a battleplan. It'll certainly save a lot of headaches and time (and money). But if you're stubborn like me, dive in and let the steep learning curve take you to hell in back. It'll force you to learn things you'd likely convince yourself wasn't important.
