I ordered a new covering from Aki-Asahi. Great place to get leatherette for a number of cameras. You can see the process below.

First removing the old covering, A dirty and time consuming job. Use any straight edged utensil to pry up and remove the old covering...

Next clean and remove any goo left behind by the adhesive. Use rubbing alcohol to clean the cameras surface. Peel up a piece of the new new covering, start with the bottom of the camera. Brush the back with rubbing alcohol to allow for repositioning before the glue sets. Place each piece firmly and smooth out any air pockets.

Let dry for 24 hours and you are good to go.
