Who has playing wear on the PRS? we've seen the sunken finishes. how about play wear.

My PRS Santana Brazilian has some arm wear. I used to play a lot sitting at the computer desk and would always knock the corner of the guitar into the desk. it started as a just being white. as i play and sweat on the guitar, it chips off very nicely. it's started out being very uncomfortable. then it gradually smoothed out.
