Oh it's starting to happen for sure. The material in both appears to be the same. Some mentions in this thread already, would be great if some photos could be shared for the non-believers.It is interesting that there still does not seem to be a single photograph of an NL Pure with degraded armour. The NL Pure came out around three years ago - surely enough time for the armour to break down if it was affected in the same way?
Probably a combination of being newer, more expensive, so there are fewer of them in the wild compared to the EL Fieldpros that have been around for twice as long.
I don't recall anyone claiming the majority of the owners have problems with the coating of their NLs. Also I'd be quite surprised if the majority of NL owners had a problem. My impression is that many NLs owned by the people on this forum live a sort of "sheltered life" - they are in many cases only one of several binoculars and not used all the time, in all sorts of conditions. Other NLs, however, are used a lot, many hours a day, every day. That obviously does make a huge difference.
By the way, two local birders (who are NOT on BF ... ) own NLs, 8x42 and 8x32. They are hardcore birders and use their binoculars a lot, every day. The NLs are the only binoculars they use. Both pairs look pretty worn already, with the armour beginning to show cracks under their thumbs. That's in a moderate climate. Neither uses DEET.
It may be worth remembering what Swarovski says about their armour:
"The armoring on the instruments in question is made of plastic (TPU). This material contains no plasticizers or protective agents, is low in allergens, and is biodegradable. As with all our products, we recommend regularly cleaning the surface of the instrument with a mild detergent and a damp cloth.
The particular properties of this material mean that optical changes such as clear abrasion, tears, and cracks may occur in the armoring when the product is subjected to frequent use." (Quote from EL 10x42 casing deterioration.)
That last sentence says it all.

Same Problem with the Coating on my 2 1/2 year old NL 8x42. The Rubber gets sticky and began to tear.
Have also a Problem with the Fokkus. Comes over time a gap in the wheel. Now when I fokkus from infinity to 30 meters, the left and right channel runs not parallel. Have to fokkus up and down, than it works. In higher temperatures it works better than in colder.
Don’t like to send it to Swarovski because the repair Time is to longe at the moment. And like to wait for a better coating in the future I hope. Think to send it in now the Bino comes back with a new but same crap coating than now.
Optical one of my favorite Bino, but the quality compared to my older and newer Zeiss is a Joke.
