My mother in law got me a new strap for Christmas. It's not a top of the line strap, but it's nice in that it's black leather (Levy's). The underside is the rough unfinished exposed part and it's leaving little light brown flakes all over my clothes. This wouldn't bother me except it's my at-work guitar. Today I'm wearing a black shirt and can't get all this crap off me.

Anyone know what I can do to smooth out the rough part? Sand it? Put some sort of goop on it?
