I’m I’ve read a few posts about ways to restore the interior chrome door trim. Most involve aluminum tape or Mylar tape. I’ve had bad luck with both of these (adhesion is poor, not easy to apply) so I decided to try chrome vinyl car wrap.
I have no experience with car wrapping but it turned out ok on a spare door panel. With some practice and prep work (cleaning, removing the old Mylar coating, and sanding the surface smooth), I think the car wrap would look very good.
The wrap material is very forgiving and stretches around corners and bends. I bought mine on amazon and used a plastic spudger stick (for electronics) to apply it. I spent maybe 5 minutes prepping the surface and the imperfections in the old Mylar tape can be seen through the wrap.
Anyways, if you have bad door trim, this might be the solution for you.
