Tamiya acrylics are great of course. This is a nice dark gray intended for IJN ships, but I find it useful for many things, like details on jet planes, details on US navy ships, etc.

Another excellent military reproduction paint, goes on nice, covers well and does not seem to need thinning. dries quickly though.

Tamiya makes the hobby paint on the planet. Its so easy to work with. The coverage is awesome. At first, coming from Testors, I was hesitant because Testors is so thin and barely covers. Once I used it, it was a game changer. I will be switching all my paints to Tamiya.
