I never said there weren't any 3rd party paints, but there are hardly any since the switch to pelt mapping on carenado planes, which is a sign of how unfriendly it is.
Possible? sure, anything is. But its far more time consuming to work with pelt mapped parts than anything else. The fact its flat textures with no paint kit isn't an issue, but different scaled parts and weird rotations and UV unwraps is unnecessary and simply lazy.
