I searched several times and didn't find anything on vapor barriers, I'm almost ready to install my new door panel from OPG these things look GREAT! had to wait over 6 months for em to be made and mailed.

I started to put them on then I realized I had no barrier so I was thinking of using plastic sheeting.

Any advice?

Been discussed many times, not sure why your not able to find.

plastic is fine. just make you use some kind of vapor barrier or your panels will be warpped in a matter of months, especially down in that part of the country.

They are called water shields in catalogs. try that way if you want it to look like oem.
