Excellent thread indeed!! I saw a link to this thread over at AGO. The microfiber systems have pretty much obsoleted my foam pads and rotary polisher in 90% of the work I do where compounding / paint correction is concerned. I'll be hanging on to the foam and rotary but they sure don't see much use anymore.
I find that most pads tend to draw the product toward the center of the pad naturally as they're being worked against the paint so as I add small dots of product to the MF pads, I place them more toward the outer edge of the pad. Maybe 1" in from the edge of the pad. The center portion of the pad keeps enough abrasives attached to the fibers naturally, so I find that adding any product to the center of the pad works to over saturate the center with product, leading to pad delamination.
I recommend to push this system further than you think it will go concerning whether there is still enough usable product in the pad after a work section is completed. Most will be surprised that usually you can fluff up the fibers with compressed air or a stiff bristle brush and simply start working the next work section without adding more product and still get the correction you desire. This practice really helps you to see how the "less is more" theory is not just a theory or a worn out old cliche when using this system.
Try it and see for yourself if you haven't already. When you can fully wrap your head around the limits of the "less is more" (especially with M-105) feature of using this system, you'll use less product, get faster cutting action and definitely destroy fewer MF pads. I do an entire paint correction using 1 single MF pad, because I pushed the limits of the "less is more" principle with these pads to figure out the absolute minimum product that would yield the results, have compressed air at my disposal for constant cooling of the pads and I practice these things constantly.
