Breaking up Dirt Shader, how?

Hey guys, I'm trying to get worn edges and I know I'm on the right track with the dirt shader as a mask with invert normals checked. However, I can't seem to figure out how to use a noise or texture to break it up a bit. Here's a simple illustration of what I mean. So I need the red areas to be more like worn or chipped, but obviously no where near so uniform.

hi rodross, you can also use a turbulence texture for this. here is an example in the standalone, the same would applicable in the plugin.
