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!
