I use a "NEO for Iwata" airbrush and HVLP spray guns with .5 or .8 tips depending on the size of the item. Lauer has a TruStrip product that is pretty good at cleaning surfaces. Pour a little on a scotch pad and it will clean and scuff at the same time.
The paint is supposed to be put on in multiple layers so each layer should be a dusting and by layer three you should have complete coverage.
The paint is not as thin as most people think so if you do a stencil, when you peel it you'll notice a seam line build up.
You can use denatured alcohol or their Trustrip to remove the paint within a couple hours. It's forgiving but expensive to make mistakes.
Their mix is 12:1 paint: hardener. You can add a sheen to the paint if you increase the hardener ratio.
