Picture? Don’t think I’ve sprayed gunmetal but I’ve seen it, I suppose hardener ratio could affect it as well as if you flashed it prior to final cure.

Can post pics tomorrow but mix was 18:1 per the chart.
Try a sample part with the same ratio but flash it off for 15m at 82C and then final cure at 121C/ 250F for 2 hours. Some colors will change at higher temps mostly the whites, and yellows, but it could be the same problem here
