To add graffitti/weathering ?

As an HO modeler/collector I would like to add some freight/engine coloring to a few models but am not knowledgeable enough to do it with any degree of sucess. Is there someplace that does this type of work or is it something that is Taboo. I know there are decals for cars but I would like something more orginal. Anyone know any taggers?/Painters willing???

Here’s a good start…http://www.trains.com/community/forum/topic.asp?TOPIC_ID=16086

A friend of mine graffiti’s rollingstock (he’s a retired graffiti artist) beyond that he doesn’t really interact with the hobby too much, but he sure does a nice job, all original.

I just do weathering.

It gets better.
I used gel pens, only the "MILKY TYPE, aviailable ay office supply stores.
www.mrhobby.com and scroll down to “fading freight cars” Black is not a good color to fade.
