So you say that you aren't sure how to duplicate that rusted vehicle or the burned out dilapidated building in your next project? Well thanks to my buddies at Massive Voodoo and their never ending desire to find cool stuff for just a few bananas we have this amazing site to inspire us all:
I know I will be using this site a lot. I have a few other sites that I follow that show old signs and buildings. "Ghost Signs" is another that offers a lot of really cool reference material both for structures, signs and obviously aging. Use these cool sites wisely!
