Been a long time since I've been here but good to be back. Hve a question re Vallejo Model Colors. Have been using them more and more and they are great to work with but am having a problem. when I apply my base coats (usually 2, thinned 2:1 with distilled water) they dry shinny in some areas ... rathy blotchy. same goes for my shadows and hightlights. I am stirring them well. Any suggestions as to what the problem is and how I can get around it. Any help would be greatly appreciated.
