i dont know if i would call them shavings, it was more like i rubbed the side of the hole, and small pieces of metal was coming off on my finger. it is like the hole is wearing away if i rub it. if you have a car with a rusted body, go hit the middle of the rust and watch it break apart, all the real small pieces is roughly generically what i had on my finger when i pulled it out of the hole.
