excellent advice above I will only add that I use the 4012 high performance reducer with my wicked and auto air, try to stay away reducing with water I know some will say they use it with no problems but if you use a proprietary reducer or equivalent you won't be stretching the paints film setting/strength properties like water can/will do, it's a bit pricey but you sound like you're doing this as a hobby so it will go along way. I Have and still do use future floor shine as well as the 5608 illustration base which is a solvent based reducer with the standard createx line and your right on pigment size is different from color to color in the same paint line so there is no one set fits all.
