Hi Brandon, I like nothing more than a rusty old car in 1/25 I hardly ever post here because what I have to say has been said by someone else before I get the chance.
A black wash is made by using a little bit of black paint with a lot of thinners. Say if your using either Testors or Humbrol paint, then use enamel thinners to thin the paint down. I dont really work to a ratio, but I guess 90% thinners to 10% paint so it's really thin and you''re on your way!. I use the thinnest brush I can find and dip it into the mix then put the brush against where you want the wash to flow, and just let the brush touch the body and it will do the rest. If you're going to put the wash into a door jamb, start from the top of the door pillar, then as it works its way down, build it up where the door rubbers would be on a real car. If you don't like the result, 100% thinners will get rid of it.
How did
