| so now, after i've moved to the 1500, sanded alot in circles, i still have scuffs.
to get the mirror finish on the last paper, sand in ONE DIRECTION ONLY
ie. up/down....not in circles anymore.
of course, as you are getting there with your lowest grit paper, all of the old machine marks from the factory lapping should be gone. DO NOT MOVE TO A HIGHER GRIT WITH MACHINING MARKS STILL PRESENT..YOU WILL RUIN YOUR LAPPING JOB!
