Of all the products sold used the ones I'd look at with the most doubt when the seller ads on "will buff right out" is a bicycle. A lot of bike owners have really funny ideas of what buffing means. Frankly I'd assume that if they say "some light scratches that will buff right out" I'd take it as actually meaning that there's gouges that are at or nearly at the metal... or maybe INTO the metal. If it turns out that they really are just minor surface scuffs then count it down as one of the luckier days you've had.
