I had to replace the moisture barriers behind the door cards on the GTV6. I used Carpet Shield self adhesive film from Home Depot - about $12 for a 50' roll. It is tough and easy to install and no adhesive is needed. Starting at one end of the door press the sticky side against the metal and unroll the film while pressing it down. Cut off the roll at the end and trim it with a razor blade. Holes for door handles, etc are easily cut out with the blade. I don't know how it will survive being peeled off for maintenance but it is so inexpensive and easy to apply that it should not be an issue.
