Try this site: http://www.alexdg.com He has lots of rust and rust-based tutorials in Photoshop. I think tht this site has some too: http://www.designsbymark.com Both are excellent pshop sites. www.phong.com isn''t too bad either, and he has a great stone texture. I found that searching for "photoshop tutorials" on MetaCrawler turned up the most good results when I was originally looking.
