Testor Enamels over Tamiya Primer

Thank you eaglecash

Thank you Tojo72

Absolutely.  Tamiya primer is lacquer, so you can use any kind of paint over the top of it.  If you're airbrushing, any paint can go over any primer/paint, as long as you're not using your airbrush like a firehose and you allow proper curing time of your paint layers.

Yes you can do it.
