Best primer for Tru-Color
Posted by Darth Santa Fe on Thursday, September 14, 2023 10:05 PM

I've been having trouble with Tru-Color paint peeling whenever I try and mask it.  Scalecoat always had good adhesion even without primer, but I guess TC doesn't bond to the surface quite as well.  What's the best primer to use with it so that I can get a strong finish that won't peel with masking?

I use Trucolor paint exclusively and have always used Tamiya Fine Surface primer under it with no problems. Use the primer in the rattle can, not the airbrush variety. I found the airbrush variety doesn't adhere as well as the rattle can.

That surprises me that the rattle can spray adheres better than the airbrush spray.

FWIW, a few months ago in low humidity conditions airbrush primed a styrene test piece and model with Tamiya Liquid Surface Primer and top coated with Tru-Color Gloss Automotive Color.  Primer and top coat both thinned 50/50 with proprietary thinner.  Primer allowed to dry 24 hours before top coating.  This morning after firmly pressing blue painters tape onto both pieces there was no sign of peeling when tape was removed.  Don't know if same would be true of a fresher coat or their matte paints.
