Perhaps quick glue is less "messy"?
Not sure, what the name is in english though... 10 seconds glue?
Cyanoacrylat glue?
Had the same problem on my d700, bought a replacement rubber kit for £40 no it looks like new.
Superglue turns some plastics white with the chemical reaction, I reparied an old flashgun a few years back it did it to that.

Superglue?
If you ever use superglue for something like this, don't use the expensive rubbish they sell in the shops. It's over priced, designed to fail and designed to block up the container after a few uses.
Get yourself some industrial superglue, plenty for sale on Ebay, dead cheap.
The stuff I have will hold over 20kg per square cm and cost around £4 for quite a large bottle (comparatively).
It would have worked on this application, but the cheap stuff wouldn't have.
