HEY,
For putting dents in: soak the body of the car in VERY HOT water for a few minutes. It may take lomger depending on the type of plastic and how hot the water is. After a few minutes, take it out and the body should be a bit softer and you should be able to mold in the dents whereever you want. May i suggest that you get this months issue on FSM and use that "Weathering with salt" technique in those areas. E-mail me at dubix88@yahoo.com if you wantme to tell it to you.
To make it look dirty: use that salt weathering technique and drybrush the body with a brown and/or a gray.
Sorry if this don't work. Post the results.
