I hear a lot of people saying tha OP has to be worked a while via a DA for the polish to break down. This baffles me a bit, as I didn't think Optimum used diminishing abrasives...so I don't think Optimum's abrasives are meant to break down, rather they use more smaller abrasives that don't break down - so even though OP is very mild, it will continue to cut at a "mild rate" as long as you continue to work it. I think this is why some say they have to work it for a long time before they remove whatever defects they are tackling.
Can anybody chyme in on this one?
