What time frame is that for say a 2x2 area? what speed?
Depending on type of paint and if rotary or PC. Pads should be a firm polishing pad for 106FF and a softer, but not too soft for 85RD. 2x2 on average paint with a good pad that has already been loaded with polish at 1500RPM takes about 2 to 3 minutes, sometimes a bit longer. Also depends how much polish is on the finish. but normally 2 to 3 is about correct.
Softer paints polishing times are shorter and polish amounts have to be limited so the polish breaks down, otherwise you start to mark up the finish with the loaded up pad as you try to break it down. You can go with softer pads and get away with too much polish at times.
Once you find the correct amount of polish to pad, then times can start to be reduced as you get more familure with the polishes. I doesn't matter which polish you use, it's how you work it and with what tools on what type of surface and it's condition.
Light swirls or marring, you can go straight to 85RD and a polish pad. Softer paints once the defects are removed, I found that a finish pad and slower speeds burnish the finish well with 85RD. More oils let it work longer than other finishing polishes.
3M Ultrafina works by ending the polishing wet, not dry. You work it to a specific degree and that's it, no working it till dust as that would be very bad with 3M Ultrafina. That polish is married to their pads and I suggest you follow what 3M tells you. They put out a few webinars on the new polish as well.:2thumbs: Great learning tool for those wanting to see what 3M has to offer.
Blackfire is unknown to me as I only use professional/large quantity product lines. It may very well be just 106FF in smaller containers, but I doubt it. I'm sure they added some extra oils for longer time. Or they could have even lessen the oil content for PC use and quicker break down. I'm leaning on the less oil/quicker break down for PC users as this seems to be marketed in that fashion. Besides, most heavy rotary users do not use small product lines, but quart bottles along with polishes mostly geared for rotary use.
BTW, 106FF also works really well with some wool pads which I use often in place of foam cutting pads as they are more forgiving and I was trained with wool anyway and feel better using them when removing deep or lots of swirls quckly. Foam cutting pads can have a nasty habbit of burning a fender area since they do not give as much as a wool pad will. YOu have more control with wool than foam. Foam cutting works best on flat surfaces, then I can switch to my SF Arnold wools. Then, foam polish pads and finish pads.
As I tell everyone, get yourself a fender and hood from a bone yard and try to learn your polishing technique on that with specific polishes and pads BEFORE you use it on your vehicle or a customers. I'd rather have someone learn it on the junk parts and burn those before someone touches their own finish. It's a whole lot cheaper to burn up pads and polish on the junk.
I hope I answered your question and added some more wisdom when it comes to Menzerna, 3M and others as it relates to polishing correctly.
