Three F5 bodies used with some regularity in a variety of environmental conditions (from -25C/-30C in the Rockies over the course of the last several winters, to +30C in the summer here at home and throughout Cascadia) and I have yet to experience problems with the rubber coverings (the "sticky rubber" problem) coming loose from the bodies of any of these cameras. Given that I had never heard of anyone having problems with the coverings prior to reading the OP (hence my initial remark, above), was "sticky rubber" a short-term QC issue for Nikon?
