Hi All!
The upper section piece of my door panels have an inconsistent indent ( a few) on them.
Please refer to picture. Is there supposed to be some sort of backing material (padding) to make this area smoother, more of a finished look?
Yep there is a foam core under the cover.
In your case the installer may have used the original cores which have shrunk.
.It can be corrected by adding foam padding to the core in the area of the void.
.However, it must not protrude too high or it will impact the opening of the vent window.--Fwiw--Keoke
Thanks,
Bob
