I don’t recall the mixing on the ALK line from Carter ( IIRC it is premixed) but if you go to a proper automotive paint store you can get the paint, hardener, and a reducer specifically for low medium or high temperature.
The correct reducer will help control flash time and reduce the chances of sagging/runs. Temperature is both the ambient AND the part…
My local shop had the PPG Delfleet line of truck fleet paint, a single stage system that worked well for me. Layed down shiny and can be color sanded if necessary.
50 degrees is like the very lowest temp to shoot, even 5 degrees warmer is certainly better….
