So I got bored tonite and decided to work on re-covering my M3. The old leatherette was brittle and peeling off in chunks, so I 'helped' it with a very fine Xacto knife. Then I cleaned all remnants of old glue (it was not the original covering, the glue used was newer) and super-cleaned the metal body with acetone and after that with alcohol. I had a re-covering kit from cameraleather.com and I put it in place. Now my M3 looks and feels new! Woohoo! I'll get some pics done in a few days, after I return from the bike trip.
