Here is a link to a thread I started awhile back. Hundreds of pictures and ideas on all manor of detail, on all sorts of surfaces including covering. You will see many ARFs detailed as you describe, with explanations of how the modelers did it.

Hope it helps. Post in the thread for more help. I'm sure guys will respond.
