In addition to my post 103: where we find problems is with the cheaper kind of binoculars of which the body is covered with a kind of plastic that becomes very sticky after a period of use and that can only be removed with an organic solvent. We never found that in the better class binoculars like Nikon, Pentax, Canon, Minolta, Leica, Swarovski, Steiner, Zeiss, PZO, Goerz, Bush, Schütz, Krombach, Hensoldt, Hartmann, Meopta, Ross, Bausch and Lomb, Beck, Hertel und Reuss, Optolyth to name a few).

Dries has a valid point. Those 100-year-old military binoculars again do not have the soft, pliable comfortable armoring of the Swaro FP. They were designed for toughness and survival not comfort.Dries, post 101,
Is this an hypothesis are is it a fact ? I ask it since I do not believe one word of your statement. If it were true 100 year old military binoculars (and we have quite a collection in our laboratory) would all be destroyed by now despite very intense use..

I have read a lot of reviews and comments that say the armor on Cannon's especially the 10x30 IS are prone to becoming sticky with time.In addition to my post 103: where we find problems is with the cheaper kind of binoculars of which the body is covered with a kind of plastic that becomes very sticky after a period of use and that can only be removed with an organic solvent.

The Swarovski coverings falling apart all had been exposed for a longer period to DEET and that causes a lot of damage.

You know that DEET will dissolve rubber and plastic when they use it to clean and restore headlights. Also, I have heard sunscreen can dissolve rubber. "The primary agents that cause rubber and plastics to deteriorate are radiation, high humidity, high temperature, oxygen and pollutant gases, and stress and other direct physical forces." Interesting article on rubber deterioration in the link below.I tend to agree with this statement, though many will say, no I didn't get any on the binocular, I swear.

As to any possible issues with Swarovski armor specifically, Swaro's decision (when exactly?) to use more environmentally friendly chemicals in their armor has been mentioned here before, though not in this thread. When the $3k+ NL is sold with soap and a brush, someone in Absam must be aware of a real problem developing.
