When I used to paint my die cast models that’s what always used for enamel paintI am very intrigued by your temperature curing of the chrome paint. Curing the chrome paint was my biggest problem. How did you come up with the temp and time?
I stared with a low temp of around 30c and work up to 80c and keep and eye on it but as long as you keep it under 120c u should be fine over that the plastic can start to go soft
