:-) I use Lifecolor paints. Yes they are alot thicker than most acrylic paints, the advantage of this is that you get much more for your money. Unlike Aeromaster paints you do not need to strain them of any bits. The manufacturers recomended thinner is distilled water, which is what I use. The ratio is more like 30/70 paint/thinner, with a few drops of acrylic flow enhancer, I use Windsor & Newton. If I'm spraying fine lines I'll cut the mix again with some (I couldn't tell you the proportion) windscreen (windshield) washer fluid. This stops the paint drying on the tip, like all fast drying acrylics do.
I've been most impressed with this paint :-) I thought Aeromaster were good but Lifcolor is better, mainly because you don't have the problem with having to strain the paint.
Like all new paint you need to experiment. HTH.
