Moisture Barrier

[JAMAS]

Is the moisture barrier anything special, or is it just plastic? While I had the door panels off (after fixing my windows) I was going to replace the 10 year old brittle plastic with some new stuff.

Any concerns with that?

Just plastic. Heavy duty trash bag is better than nothing but you can pick up some heavy guage plastic sheet material at any hardware store (it'll last longer).
