It does have a little more but you can alter how they cut by what pad you use. 85rd is a favourite for jeweling using a black or blue pad.
Bingo! Although both are "finishing polishes" by description, 106FF does have some cut to it while 85RD has no cut but can produce a nicer finish than 106FF. I like to keep things simple. Power Gloss for compounding, SIP for polishing on a variety of pads and 85RD for finishing.
same for me. my usual polishing processes are: -M95 + tuf buff wool for compounding -SIP on a variety of pads. use on a white or black pad for 1-step polish -106ff i use on a green pad. i barely use it. -85RD for finishing on a black 3M UK pad, blue 3M UF UK pad, or black CCS pad.
