This is a collection of 30 high-resolution grunge leak -brushes. Sizes are mostly around 1600 px in width with a few at 600 px. They are useful for creating things like rust or old concrete but I'm sure you can think of many other uses as well. File format is ABR so it should work with every version of Photoshop.

What you are NOT allowed to do:
Redistribute, repack or sell these brushes and/or claiming them as your own
