Red Hydro LC pad was my first testing with 845.
Worked nice. 845 when warmed up ( if you use this method ) and a sprayer head mounted on the bottle, nice spray prime to the red Hydro pad, and off you go.
This is considering that the polish and Glaze ( if you go that route ) have already done their job, all you need is a thin coat.
I used the PC with the Hydro pad to apply on either a 2 or 2.5 setting.
Just got my PO85rd today, so I cannot comment. I would think Black ( that is what I am going with ) It is very low abrasive so any amount of work would need to be via the pad.
I have used 106 on the Opti Polish pads with good results.
I tested the top end of working SIP / 106 on Opti MF pads on solid surface counter material.
I used a screw driver to put marks in the sink cutouts, to see what it would do on something like this. Other half of the sink cutout is going to be Opti Hyper combo on Opti MF pads to get a compare.
White ( if LC white pad ) is a big aggressive for applying wax in my opinion.
