What's the best covering paint with 1 pass with the airbrush?

Recommended Posts

Hi Everyone,

    Here is the scenario:

 

1 You're painting a light color over a medium color.

 

2.  You are using an airbrush with a .2mm needle.

 

3.  You are making an exotic camoflage pattern.  Many fine lines and curves very close together.  You have to use lower pressure to maintain a pencil thin line with your airbrush close to the surface.  You cannot go back over a single pass.

 

What kind of paint would you choose?  Enamel?  Lacquer?  Acrylic?  Or oil?  Brand?  And is this brand easy to acquire?

 

Thanks for your thoughts.

1 you don’t need to lay down the paint in one pass

 

2 use MRP

 

that’s all there is to say

But indeed, I do.  Replicating the pattern of pencil thin lines will be impossible.  I experimented with MRP, Tamiya acrylics, and Tamiya Enamels.  The Enamels did best but dry-tip was a problem.

I got very good results in the past with Gunze Aqueous and Tamiya paints using their own-brand recommended thinners. I also used Lifecolor acrylics and Xtracolor enamels with good results. I think that 0.2 mm nozzle may be a problem. That kind of nozzle is intended for inks. Paint pigments, however fine the grain, may not pass that easily through such a small aperture. I do not have a 0.2 mm airbrush, the smallest I have is 0.3 mm, and I was able to make very thin lines and small mottles. Even bigger nozzles can yield good results by adjusting needle travel and air pressure. Airbrushing is about flow of air and paint and such flow is easier to control when you have enough of both.

The "correct" answer is none! I have not found any paints that will do what you want them to do in a single pass. Some paints are better than others in coverage, but fine & tight airbrushing requires thinned paints (especially with a 0.2 nozzle) and that means less opaque coverage. The "new" crop of acrylic lacquers (like Mr Color & MRP) are better at this job, but still require multiple passes.

I was afraid of this.  But I also have a .3 nozzle airbrush which I assumed would be less apt for the job.  But Radu's post show me to be in error.

 

But even with it, the MRP lacquers aren't up to the task.  I will experiment with the .3 nozzle and the Tamiya acrylics and Tamiya enamels, too.   But my Tamiya enamels have been around a few years and reconstituted a couple times, and not always with the gentlest of enamel; thinners.  So, I have a pot of Humbrol enamel on the way with some Humbrol thinner.  If I can't get a satisfactory look from either of those, then I may have to give up and find a different scheme.
