On our '08 coupe I've noticed a tiny bit of fraying on the stitching around the seat bolster, right where you'd drag your butt across it when exiting or entering. I'm worried this will get worse over time. a couple things I've been doing to slow down the wear on this area:

1. I took a bar of beeswax and rubbed it along the stitching, with the thought that it should keep the stitching's fibers together. Anybody have thoughts on the beeswax idea?

2. I put my left hand over the bolster when getting in or out, that way the leather is not being abraded as you slide in and out. I got this tip from another car forum.

3. Lexol leather conditioner every couple weeks. It this too frequent?

I've looked at XF's that were several years old and did not see excessive wear around the leather or stitching, so I assume they use decent leather. I've had other cars with Connolly leather and the bolsters looked terrible after 5 years.
