Danny you twit.... :-)
Danny,
What if it DID somehow get a few "fibers" from the strip pad onto the cotton? You are spinning the freekin pad on crappy dirty nylon carpet anyway. Do you worry that your little pads may get dirty as well?
I'm sure you've used similar buffing pads for encap work. Do you likewise fret over a few fibers getting out of place? If nothing else your cotton pads may pick up a little agitation improvement similar to the green stripe bonnets.
Bottom line: New strip pads work great to drive thin cotton pads. I prefer not to use red pads unless working on red carpets, and of course any USED pad may shed more and grip less.
OK, you can ride the horse now....get on and I'll insert a quarter,
Lee
