Hi guys
I cut a very thin sheet of aluminum obtained from the aviation dept at home hardware. There is tough building paper bonded to the back side.
Cut this to fit the floorboards but leave a lip about 3 inches long that slides under and between the rudder pedal bearing blocks.
This is not attached to the wood floorboards but is screwed down with the floorboard screws.
It is super easy to keep clean. Easily replaceable if necessary. Looks great and is light.
