Two questions

Backflushing is blocking the tip of your airbrush (using a rag or wad of paper towel/tissue) to redirect air back through the paint path, blowing paint back into the paint cup/jar.  

Personally, I would perservere with your existing double-action brushes rather than invest in a single-action brush. With a  little (well, ok, a lot of) practice, you will have more control than you would a single-action brush.

For a single-action airbrush, in my opinion you won't do any better than a Paasche H. I've been using mine since about 1964 and it just soldiers on. It does everything I need an airbrush to do, and I used it for years in professionally painting model railroad locomotives & equipment. I have a second one in case the first ever dies, but I suspect I'll go first. I have an Iwata double-action airbrush that I've never bothered to use--yet.

I'll second John re: the Paasche H. It's a brilliant single-action that's absolutely bulletproof. Better still, the paint only ever travels through two removable parts, so even if you make a terrible hash of things, you can (cheaply) replace those and basically have a brand new airbrush.

BUT...I couldn't imagine using a single-action for detail work if I had double-action on hand. It'd be like hitting a twisty mountain road in a delivery van versus, say, a Mini.

For base coats, though, it's greatness.

Hello everyone,

I have a couple of questions. First, what is backflushing? I have seen it referred to numerous times and would like to know how to do it.

Second, I am in the market for a single action airbrush. Mainly for detail work as I have two badger double action brushes. I would love to hear your opinion on the top single action brushes.

Thanks,

William

What are the problem with your 2 Badger double action in doing detail work and what models are they? The Badger Krome is perfectly capable of doing detail work.

It is not impossible to do detail work with a single action airbrush, but you need super refined skill to do it. A good double action provides much better user control of the trigger than that of a single action.

There is a good video on back flushing at Ketts Cosmetics of UK.

As Kei Lau wrote, the Krome will do some really fine detail.  And, with its needle limiter, you can use it just like single action, only better.
