Just found this thread, everything's coming along great. Read through it all but I don't remember reading about a color scheme??? And just my two cents but while I haven't used spray cans (yet), I know when you're dealing with ceramic glazes through an airbrush, it's an actual technique to spray further away because basically the droplets are pseudo drying before they hit the surface creating that gritty texture. So I'll bet it's the same with regular paint as well. Can't wait to see more, and good luck with the speed building lol.
