+1 to Max and the others. Know how much pin u want, not too much not too little. Make sure it is filed flat ( the more time u take making sure it looks good and flat the better ur end result will be ) Lots and Lots of tiny taps in a circular motion , I personally count the taps I do to make sure its even before i do when polishing I dont use white rouge because on me it tends to get stuck underneath the bottom stacked washer, ,so I stick to mothers mag and micro mesh usually. If the dimples are really bad Ill use sandpaper to take em down.
