If I were going to skin the sides on an MC-9 it would be an all or nothing deal. No OEM windows left at all, just RV windows. So I would buy another sheet of aluminium and do it all, then install my RV windows with appropriate framing where I wanted them. 090" is a great choice, and you can cut it wasily on a regular table saw with a wood blade, just have a helper, ear protection and a face mask, not just goggles.Brian
Aluminum will wave like old glory with heat steel is by far the best for no waves
.... just didn't expect to spend that much on the outside.
