Airbrushing milky / haze finish after vanish
Posted by Reddogbobcat on Tuesday, April 9, 2024 2:02 AM

Hi All,

Have returned to modelling in my retirement since my last build in my teens.

Started by building some basic WW2 aircraft via hand painting followed by gross vanish, decals, another clear gloss, pin wash and finished with a clear Matt. No issues with paint reacting with vanish for a reasonable finish after such a long gap.

Have since moved to using an airbrush and had some issues with the paint finish turning milky or having a have. Not sure where the issue is and would like to ask for some advice?

Steps followed as per below:

  1. spray primer from a can (Tamiya)
  2. airbrushed model with thinned Tamiya acrylic 
  3. gloss clear (Humbrol) applied via brush
  4. decals and softener
  5. clear gloss again - first issue seemed to have light areas like it was the primer (found advices online to applied another clear gross, this seemed to fix the problem)
  6. pin wash on panel lines
  7. applied clear Matt via spray can (Tamiya) - second issue it dried milky or had a haze on finish but on on the top side of the model that has a darker green paint, the underside seemed to to fine.

At a bit of a loss why this happened and would appreciate any advice.

Thanks.

Was the haze there before the flat coat,flat can have an adverse effect if sprayed from too far away,if flooded on,or too much humidity.For best results,just mist it on in light coats,get clears that can airbrushed,easier to control.

No haze before Matt vanish, but had spotting between gloss coats. Thinking back I may have held the Matt spray too far away, can't remember about the humidity on the day, but will bear in mind for next time. Thanks.
