I was trying to use some Woods & Water Rich Brown paint today. I bought the paint last summer and today is the first time it was opened (the seal was still in place). The paint was really thick and I could not get it to spray from my Paache H1 airbrush. I thought maybe I didn't shake it up good enough. I cleaned the brush,cup and needle then shook the paint vigorously for about two minutes. Still thick. I added lacquer thinner. It still wouldn't spray for crap. What did come out was thinned out and was a "spit" not a steady flow by any means. I added retarder wondering it it was drying at the tip. Same outcome. So I tried some Woods & Water pure white. It sort of sprayed but was very difficult to keep it going. If I stopped it was heck getting it to start spraying again. I am not blaming the paint or airbrush as I am myself but I don't know what else to try. Suggestions? Video recommendations?
