Yes, the CG S5 will be a next generation alternative RMD and I don't think you will have any issues looking after it....coated and protected it will be fine...one of my RMD's is stripped and I live in the wetest part of England and it is clipped to my Daysack or Bumbag whenever I go out walking which is daily...and no problems...HD has one the same and lives on a salt marsh...no problems either....sometimes storage rather than regular use is a bigger risk...use vasiline and it will be fine...
