After about 12 hours of flying I noticed that the threads on my right hand strap were starting to fray.  This seems to be happening due to the strap rubbing on a retaining clip as the canopy pulls the strap upwards as it starts generating lift.  To prevent this I bought some UMHW tape and wrapped it into a tube around the area that is rubbing on the harness strap.   The UMHW has adhesive on one side so this should allow it to stay in the tube shape I rolled it into.  I have about 50 feet of it so I can make plenty more if it needs to be replaced at some point.  I’m hoping that this will prevent any more chaffing of the harness.
