Ok, thanks a lot! Whats the difference between Vallejo MC and Air Color?

I'm a newbe bare with me lol

Vallejo MC, or Model Color (white cap), is primarily intended for brush painting, though it can be thinned for airbrushing.

Vallejo Model Air (black cap) is a thinner blend for intended for airbrushing. It's often said to be "airbrush ready" but depending on your particular airbrush, it may need tweaking to find the ideal viscosity.

If you are talking about Vallejo Air, it is specifically formulated for an airbrush. 

For cockpits, as for me, I always use Tamiya fine primer first, then usually air brush Model Master acrylic for the specific cockpit color, then pick out fine details with Vallejo paints, then give is a coat of Testors Clear Flat.  I have never had any problems with this.

Steven,  Priming, the cockpit areas is not necessary,  But I do use Modelmaster Enamels.  They cover very well and bite into the plastic.  If it could save you time and a step it might be worth it.  Rick

Do you think painting Vallejo over the tamyia airbrushed base would work better?

That's definitely an option. I often airbrush a base of Tamiya acrylic before brush-painting Vallejo ModelColor. I find that The Vallejo MC does not "burn through" Tamiya acrylic when brush-painted over the latter.

Thanks a lot Phil. I was thinking about putting enamel paint over the airbrushed details, I was just worried when I did my wash it would screw it up more...

Brush painting any paint over an airbrushed coat (of a similar base paint) can be problematic due to the thin layer of paint being over-coated. This is particularly so of Tamiya crylic paint.

Before overpainting, ensure that the first coat is fully cured, not merely dry. Tamiya acrylics will dry in minutes but should be left to cure for 24 hours before overpainting or applying  masking tape.

When brush painting over an airbrushed base, the solvents in the paint will make short work of the thin layer underneath and burn through very quickly.

One way to avoid this is to overpaint with a paint of dissimilar type. eg. brush paint acrylic over an enamel base.

If you must brush paint Tamiya acrylic over a Tamiya acrylic base coat, work quickly, do not "work" an area more than necessary and avoid overloading your brush as it will introduce more solvent to the area and increase the risk of burn-through.
