What paints can go onto other types???
Posted by SNOOPY on Sunday, December 9, 2007 6:56 PM

A couple of months ago I painted a cockpit of a warbird with acrylic (Tamiya) kakhi.  I want to brush on flat black (thinking Testors).  Can I put enamel over acrylic even after a long curing process has taken place?  I can not remember that order of things except the oil can go over all but nothing can go over oils.  Does anyone know whether enamels can go over acrylics?  I have Tamiya flat black but I have had not a lot if any success brushing Tamiyas.  It airbrushes nicely but for some reasoin brush well it stinks.

You can put enamel over acrylic provided the acrylic was applied to a clean surface, and is fully cured. You can put acrylic over fully cured enamel. You can put an oil wash over acrylic, or an acrylic wash over enamel.

As for brushing Tamiya, there's a trick to it: Decant a little paint, dip your brush in isopropyl alcohol or Tamiya thinner, then apply the paint. Each time you reload the brush, dip the brush in the thinner or alcohol first. And always paint with a wet edge.

This trick does not make the paint to thin to paint with?  Also, I have always read about the paint with the wet edge.  What if you are painting a large area where you may have two or three edges?  I never seem to get a nice smooth surface.  I have seen some really nice paint jobs with a brush but I do not seem to get the hang of it.  Thanks for your help.

It is possible to brush paint large areas successfully, but it requires patience and practice.  Airbrushes and compressors have become much more affordable. Airbrushing requires patience and practice, too, but  the learning curve is much steeper.

No, this technique does not make the paint too thin. You are just dipping the brush very quickly in the thinner. I recommend that you try this the first time using Tamiya's thinner. If not, add a tiny amount of acrylic retarder to the thinner if you can.

The other thing with Tamiya is to keep the brush wet and lay the paint on relatively heavily. You  want just less than will cause a run. Takes time and practice.

Good luck!

Thanks for the info. Fortuneately I only have to paint a small area, a rudder stick and the boot at the base of the stick.
