I'm doing some shading on my current mini with some MSP Burgundy Wine. I have it really thinned down to about 1:10 paint:water. After several passes I noticed it started to get a chalky appearance.
I used the same color as a base coat on another part of the mini with about three coats and had no problem there. It was only when I thinned it out to glaze that it started to chalk up.
What am I doing wrong and is there a way to correct it?
Thanks!
