Yes! I've never seen this paint process before, and all I can say is WOW! Of course, this paintjob might look better on a metal body gun (m4/scar/mp5 etc.) than one with wood gaurds,(even if its the black version). I say do it! With sponging, you don't even need spray paint but you have to make sure it will stick.
One color? No problem. Just sponge the color onto the metal (tan sponging on black). You could always add more colors when you get more paint.
