Here is some of my own photos of rust and grunge stuff. Most of it is a dumpster in a neighborhood. Originally I was planning to use them for a video editing but I never done it, so decided to share it with anybody who needs some free texture for any type of projects. These are all royalty free and you can use them in your art project, but please do not put them in your texture website without my frog link. Just right click and save them.
