Primer for acrylic paint on plastic models - Model Railroader Magazine

My fav. spray can primer is Tamiya's lacquer based Fine Surface Primer, goes on nice and as Doc Wayne says, nearly as good as using an airbrush.

Desiring more control I gave Vallejo Acrylic-Polyurethane Surface Primer a whirl thru my Badger Patriot airbrush.  First try was 2 drops Vallejo airbrush thinner to 15 drops primer, went on okay, but with some spitting and internal brush clean-up was a chore.

Before a second try saw a youtube vid that suggested 50/50 mix primer and thinner.  Big difference, went on real smooth with easier clean-up.  Didn't do any sanding, but heard that this primer will peel if sanded before competely cured.

Got some Tamiya Liquid Surface Primer on order that I'm eager to shoot.
