An old thread yes figure an update would be useful.

The shop where I'm apprenticing currently uses Armacoat because it's Canadian. The problem is they seem to be dropping the amount of colours they have. We are currently looking at moving to duracoat for the better selection.

Dismissing the amount of colours, Armacoat works perfectly fine and hardens pretty good in my opinion. I've torture tested one of my guns that I had the barrel armacoated and it's survived quite a bit. Without an oven to bake parts, it takes a total of 21 days for Armacoat to fully harden.
