Kframe, engine bay, front suspension questions

Thanks, I'm going to ask the supplier about sanding between coats. Flash time is approx 5 minutes, but there's no way I will be able to get all coats on before its cured.
Maybe keeping cans inverted while.not being used may help with mixing
I'm thinking 600 grit between coats?
Heads up- I had the local paint shop match my EE1 dark blue ploy in Spraymax 2K cans. Used same day and continuously agitated, the last 1/4 of the can sprayed very dry with LOTS more metal flake. Maybe caused by how or who mixed the paint or filled the cans, I dont know. Keep a sharp eye…
