I\'ve actually tried some vallejo matt medium in with the paints that I\'ve been having a problem with and it seems to have cured for the most part. I mixec one part paint, one part medium and 4 parts water last night and it seemed to take a LOT longer before the paint began to separate at all.
I wonder what brands of artist mediums will mix that well with them, as the vallejo bottles of medium are so small. Liquitex is quite common around here (NS Canada). Has anyone actually mixed that in with vallejo paints with the same success as their own brand of medium?
Actually in the GW line I use pink all of the time when I\'m going to paint bright colors over black. GW pink covers really well and red orange and yellow go over it great.
