With a coat of Gunze Sangyo on my Fw-190 I applied a coat of Tamiya. After a few minutes cure time, the paint crackled ! Is there a basic incompatibility between the two? I suppose next time I'll just abraid the surface and clean with grain alcohol. Any other suggestions?
Both were acrylics. Airbrushed of course. Low humidty with a temp in the fifties. The latter condition I thought was the cause initially.
