i found out the hard and stupid way that a green pad is NOT the way to take out scuffs. luckily it was on my cheapy frame (the ross one).
tried a new way with the new frame, and found that those MAGIC ERASERS (the ones for household cleaning) is THE way to take out light/medium scuffs in the paint that soap/water/washcloth will not take out. this did not scuff up the frame at all. there is no noticeable scratches in the paint, and all the black scuffs went bye bye very quickly.
i can take close up shots if anyone wants to see where the scuffs were. can only see dips in the paint now
