How do I remove reflected objects from metal surfaces and replace with other reflections?
I want to take this picture of an Airstream (that was photographed in a parking lot) and place it in a forest. So I have two (2) problems:
1. How can I remove the original reflections and...
2. How can I make realistic reflections of trees and other things that might be in the forest (trees, grass, streams, etc)

I have a lot of shiny objects that I'll be shooting (and CAN'T move), so this is a technique, or several techniques, that I need to learn.
Thanks for any help!
