These get great reviews. They go on great with a brush. But I'm struggling to airbrush them. Looks like some people thin and some don't. Most seem to say that they are airbrush ready right out of the bottle. But I'm having no luck. The most common problem is after about 30 seconds of airbrushing my airbrush gets clogged. I have no problem airbrushing other brand acrylics. Am I doing something wrong or should I just thin them?
