I have 2 Leica M cameras, M2 & M3 that were taped up quite a few years ago with black masking tape. I would like to remove the masking tape and clean them up in order to sell them. I can tediously scrape the tape off with fingernails but it leaves a sticky residue. I'm looking for suggestions on how to best clean up the chrome or whatever the finish is. So far I've gotten a few suggestions but I'm open to whatever might be the best/easiest way to eliminate the sticky goo. One repair guy suggested alcohol or Goo Gone. Is Gus Lazzari out there, feel free to join in. It's a project I am going to get done and would like to get it done as elegantly as possible. Thanks, Gil!
