R1DER said..A few years ago the boom grip wore away under my harness lines. I haven't done anything about it.
Just wondered do other people fix it? Patch it? Or just leave it be?

In addition to the worn grip around the harness lines, my severne had a large area on the left side with the grip gone. (Right side for some reason is still fine). Re-gripped with a piece of 40mm shrinking tube thingy
www.amazon.com/dp/B08V19VSFQ? 95% of the work was scraping off the old grip, I used some paint thinner but still it took a while. Putting on the new grip with a heat gun takes five minutes (and is fun to watch!). I used no glue.
It looks pretty good, and it is a bit thinner than the original!
