Don't like the idea of rattle cans on models, unless very large scale. No matter how careful or precise in the application, there's just not enough control over the pressure, spray pattern or weight of paint.
I think you'd be better sticking with the airbrush, and maybe use a fresh bottle of paint. I've only ever used Vallejo Model Colour - where thinners is needed - and never had a problem. Also, I found it better value for money, as it's the same amount of paint as the Model Air, but twice the coverage, due to thinning.
