Some mildew/moss/algae costume question.

[Dr. Giggles]

I am in the process of making a messed up old zombie. A well dressed zombie of course.
But my question is, how do i get the looks of moss, mildewy or rotten clothes look? I have a black suit jacket, a torn up white dress shirt, black slacks. I have tried smearing dirt and all that. But it just doesnt have the look i want. Like the zombie was in the ground for a long time who only recently rose up. Course' theres going to be mildew and moss on their clothes right?
I am having a real hard time making the suit look like that. I need a look that will last obviously.
Because all my attempts with dirt and mildew and algae all fail because it falls of eventually and i need it to last.

Doc,
I like the look of airbrush for mildew, just do a few spots of green in a few different shades of green.
For moss I dip spanish moss in colored latex (green or light green) and normally add velcro to the bottom of the patch so I can remove it for washing.
Belt sanders give a good aged look and I use spray paint alot instead of actual dirt.
Good luck with it,
Allen H
