Okay, so I know there is no magic formula for mixing/thinning your paints. However, I read somewhere that Windsor & Newton\'s Flow Improver was a good product for thinning. I was curious if you were supposed to mix this stuff with water before adding it to paint. The reason I ask is because I have been adding it straight to the paint using about a 4:1 ratio. I\'m mostly pleased with the results except more often than not my paint has what can only be described as soap bubbles in it when I apply it to my mini. There are no bubbles on my palette, only on the mini. If I don\'t get rid of these before the paint dries then they leave a mess. So, should I be diluting it before mixing it with my paint?
