Nikon do literally use double sided tape to hold the rubber on, at least for some bits, and this works generally very well. At any rate, Nikon SG won't allow user-replacement, Nikon US will mail the parts for a nominal fee (like, under US$5 and shipping) and thereupon it's a 2 min fix, no fuss. And Nikon UK, bless their cotton socks, will ship the parts for absolutely nothing.
That's very nice of them! Nikon SG wants $25 for parts and labour for replacing the rubber grip of my Coolpix 950. The 2nd time it fell off, I can't be bothered to replace it anymore. Just remove the double-sided tape. ;p
