Do these in the airbrush and brush painting dropper bottles need thinned prior to using or are they good to go right out of the bottle like the Vallejo Model Air paints are ?
If you mean the stuff with the orange caps (usually) that come in the sets then yes, they are airbrush ready. http://www.ak-interactive-usa.com/modulation.html#paint
Under the AK logo it says airbrush on the ones I have.
No idea about primers sorry.
They look like great product but seem a bit spendy to me considering what I can get the Vallejo Model Air for ????? This Military stuff is all new to me but I need to increase my arsenal of Military colors as Ive been bitten by the Military bug hard lately. Just got 5 new kits that are all Military related and not automobiles. Just trying to weigh my options of what is the cheapest way to get them. Gotta save a buck where I can hahahaha.
