The 5.5inch orange pads and
M105 is a pretty good combo.
A few users have experienced how it dries really quick with a rotary. Not enough lubricant/oils and too much abrasives. Humidity is a problem and M105 can start dusting really fast. Some have mixed in a bit of optimum polish to increase the working time, but it will also reduce the cutting power slightly. Though if you want longer working M105 then you may as well buy
M86, slightly less cut but longer working time just like adding optimum polish.
With the orange pad annd M105 surely that provided enough correction? That should be able to remove heavy swirling on most paints.
