Razer Mamba 16000 Repair

I have had a Razer Mamba for roughly 6ish years now, and I have loved it the whole time. Unfortunately I have run into an issue with my mouse and it is out of warranty (not that I was expecting it to be still covered by warranty anyways). The side grips of my mouse have started slipping off of the mouse, is the grips themselves are still in great condition but the adhesive itself seems to be beginning to fail. Are there any recommended adhesives or a way to reach out to Razer for an out of pocket maintenance or something along those lines? Like I said, I very much love my mouse and would love to keep it for many more years.
