@Tojo72: the chart isn’t saying you can’t, what it is saying is that you won’t have miscibility problems if you use like with like, or less hot over hot paints.
The problem with these discussions is that we all have personal experiences where we’ve done it differently. Here’s another way to look at it from Tamiya:
PAINT COMBINATION INFORMATION
• Base Coat Acrylic/Top Coat Acrylic-Compatible
• Base Coat Enamel/Top Coat Acrylic-Compatible
• Base Coast Lacquer/Top Coat Acrylic-Compatible
• Base Coat Acrylic/Top Coat Enamel-Compatible
• Base Coat Enamel/Top Coat Enamel-Compatible
• Base Coast Lacquer/Top Coat Enamel-Compatible
• Base Coat Acrylic/Top Coat Lacquer-NOT Compatible
• Base Coat Enamel/Top Coat Lacquer-NOT Compatible
• Base Coast Lacquer/Top Coat Lacquer-Compatible
These are general guidelines. As I said in the earlier post, follow them and you mostly won’t have trouble. Can you disregard? Sure. But then you start getting into territory where experience plays a huge factor.
