Minor lens repair issue

[JSD]

I have a question for anyone who might be knowledgable about lens repair. I have a Nikon 80-200 zoom who's rubber zoom grip is loose. Especially when hot out I need to grip excessively hard or the rubber simply slips. Can I glue this with a few dabs of rubber cement? Or should I take it in to a pro repair shop?
Thank you,
JSD
