I use Gamma Guard, which is virtually the same as gaffer's tape. I place it from 8 to 4 o'clock mostly to protect the grommets and guard for my POGOS which have or have not, depending on what I read, been discontinued.
Before I press the tape in place, I cut slits every few inches to try and avoid crimping around the curved edges. My rackets were both bought used with several nicks and scratches, so the tape tells me how many I put on myself. So far, only one.
Weight is negligible… I don't notice at all.
