Six brushes that use procedural masks, based on experiments I did with the basic brushes from before.
Barnacle has a weird round bubble effect.
Braided Cable gets a mesh woven feel to it.
Chalk has a better look as far as what I expect from a chalk board result.
Circles is based on an early brush I used to make to block out better 2d forms that I would dress up.
Drybrushing has a broken, chipped paint feel.
Stencil Digital uses a procedural that is set to Cell noise, and set to stencil so you can use mix of multiply to get a faint space ship decking look.
Tread bump is just an interesting pattern found by tweaking the normal magic texture.

I hope you have fun!
