So continuing the KV, I thought it was too yellow so I mixed up some blue filter to counter the green.  Definitely toned it down, I like it!  I mixed Tamiya clear blue with some Mr. Color leveling thinner 400.  
Above you see the finished model.  Much better. 
Next after some drying time it was time to add scratches.  I actually touched up the pin washes and mixed up a lighter green from the 4BO color.  These would be scratches that have not penetrated the paint through to the steel.  
After the light 4BO color, I used LifeColor Burnt Metal to do the deeper metal scratches.  It looked great.  The LifeColor for some reason have it some relief.  
 Then I decided to do some fading with oils.  I used too much white.  Learned that lesson quick.
I think this looks fantastic!
Streaking time. 
Streaking looking good
Test fitting spare tracks.
Time for dust and grime.  I mix 50/50 the colors above and lightly spray them on lower hull.
I used pigments on the flat surfaces, then use White Thinner to start getting the dirty look.  I got those bottles YEARS ago when Mig Jiminez still owned the company.  Pigments last, especially if you don't build enough....guess I need to build more. 
After whiping them off with a number of ear cleaning buds and make-up applicators. 
Wheels on left side have pigments, and the ones on right side are clean....for now.  You can see the difference.
