Mix ratio for Tru-colors paint?

[Green_Elite_Cab]

I've been working on some F&C kits lately. Got to the point for painting and figured I'd give Tru-colors paint try again(They had the prototypical color for this particular boxcar). Tried paint directly out of bottle in my air brush as stated it can be used. Paint came out dry and caused a rough surface( I should have experimented on a scrap piece of styrene or something. Lesson learned). So, boxcar has been stripped and I am preparing to paint it again. 

Anyone use Tru-colors a on a regular basis and have a ratio for paint and thinner that seems to work well? I did pick up a bottle of Tru-colors thinner, so I have that on hand.

Thx,

Mark,

I specifically bought a set of Micropipettes (precision liquid handling equipment) specifically to find out just how much Tru-color needs to be thinned.  I bought a P1000 (100-1000 microliter) and P5000 (1-5 milliliter) pippette, which should be able to handle most jobs.  the disposable tips are ridiculously cheap when bought in bulk and unsterilized,  so I'll probably never run out. 

I have had the same problem using Tru-color out of the jar,  sometimes it settles,  sometimes it looks awful.   I think I had success with 1 part thinner to 3 parts paint,  but  I don't remember.   

In any case, as soon as I get some tips for my 1000 ul pippette, we're going to know within a ridiculous degree just what volumes are necessary to make paint go through well.
