Is acrylic enamel compatible with base coat clear coat or are they like lacquer and enamel? Was going to shoot the inside of the cab of with single stage acrylic enamel and shoot the outside with bc/cc.

As long as you used hardener in the acrylic enamel and you allow it to dry sufficiently, you should be OK.

if you mask off the inside while you're painting the outside there shouldnt b an issue
