M86 uses the new non diminishing abrasive similar to the M105 that everyone here loves.
M86 solo creme i would say competes with Menzerna SIP in my opinion.
As the abrasives do not have to be broken down M86 is awesome with a DA polisher unlike SIP that will leave a marred surface until the polish's big abrasives are broken down into smaller abrasives. Probably one of my favourite polishes, with a polishing foam pad its great to remove moderate swirls and with a wool pad its great for heavy swirls.
With the solo pads. I've recomended them a lot. They are the easiest to use pads on the market by quite a margin. However they are expensive and do not last very long. So great for starting out with a rotary but not so good for bulk detailing.
