Cant help because my doors dont have a plastic lining, but they may have at one time.
As for the show, I watch it from time to time. I have about 10 of them recorded I have to get to one day. I agree their schtick wore off on me a couple years ago, but I still enjoy watching and usually learn a thing or two.
AFAIK its the only mopar show out there, so I have no choice
I also enjoy fast and loud, and that show has another ass who is almost as unlikeable as Mark, but I can look past that stuff.
I think Richard is really like his character in real life though. When we got our $100 refund back at the Dallas gas monkey show (along with about 2000 other attendees) everyone got an envelope filled with one dollar bills.
