The November Mustang Enthusiast has an article on this. Looks like a good idea. When you open your trunk, you see an unfinished, poorly painted area staring at you. This will cure that quickly and can be customised to your tastes. Check out www.granddesignmat.com for more info.

Not to be a smart-a$$ - but try the search feature. Many topics in here are beaten like a dead horse [8D] These things are cool, but I like mine best because I made it by hand, and it covers the ENTIRE trunk lid/rear section - not just the top.
