Hi guys, I have some questions regarding airbrushing and paints. I currently have been using Lifetone Paints (Water based) with mixed results. I find it hard to to control my paint flow and get hot spots and spider webbing. What causes this? Do I need to thin my paint, and if so what is the best way (water, thinner, rubbing alcohol etc)? Another question I have is what exactly is retarder and should it be used through out the whole painting process? Any insight is greatly appreciated, I thought I would learn this stuff in Taxidermy School...but we just poured from the bottle and sprayed.
