Gluing a partly unattached rubber

Hi! While playing, I noticed that a part of my black rubber unattached from the blade, what should I do? Should I glue it directly or should I remove the whole rubber and glue it again?

Here is a picture: https://www.dropbox.com/s/993am3g92aiwfwe/New%20Doc%206_1.jpg

Thanks in advance!

Hi Danison,

It is better to remove the whole rubber if that much is coming off.  If you try to just put some glue under there you often end up with a ridge.
