I recently noticed some scuffing on my drivers outside bolster along the stitches. My entry and exit methods are alway very careful to avoid wearing on this surface.(I put new leather on my old Z car PITA) I think the edge on my Xfire is getting abrasion from the seat belt dragging across the sitching so I have been more carefull how I drag it across. Meanwhile I will order some leather dye. My seats are more charcoal grey than black, close to RC8 Dark Mist Grey. Toddy, give us a post if you have tried the dye on your seat.
