Fettastic
Active Hunter
I was able to do the spatter, rust, and grease stain on the right side of the helmet as well as attach my RF topper. For the spatter I ended up using 3 different colors. I wet a brush with relatively stiff bristles with the paint I want to spatter. Then I'll flip the brush upside down, and brush my finger across the top of the bristles to flick the paint. I practice on a scratch piece right before moving to the helmet to make sure the effect and consistency of the spatter is correct. Then after I get the effect I want, I'll go back in and topically apply the more predominant spatters and shape them as best I can to reference pictures. It's really stressful but fun. I also do the stock un-attached to the helmet since there is a lot more rust on it.
