I've never used Mig Ammo paints. And it's been years since I switched away from Model Master rattle can lacquer gloss and flat coats. BUT.... generally speaking, I have had no problems with enamels over acrylics, as long as the acrylics have had time to dry AND cure before the dissimilar paint is applied.
Do you have a "paint mule" to test it out on?
F is for FIRE, That burns down the whole town!
U is for URANIUM... BOMBS!
N is for NO SURVIVORS...
