I am trying to paint bad moons orks so i got some iyanden darksun and knarloc green, watered it down and started painting. I noitced that it left these weird looking squiglly lines and bumps, more notciable on the darksun then the green. I dont get what im doing wrong as all my foundation paint seem to be doing this. it almost looks like thiers bubbles and tiny bits of hair in the paint after it dries,and looks really rough. Any help?
