Last night I discovered that a friend's leather jacket buckle damaged one of the upper side bolsters of my passenger seat. The leather looks like it was "keyed"- erratic scratch patterns easily visible in daylight or with a flashlight. Pretty upsetting, but is there is anything I can do repair-wise? The leather didn't feel scuffed at all, but I don't know too much about leather per se. Polish? New patch of leather? Any input is well appreciated.
