I'm curious if anyone has used Meguiar's Fine Cut Cleaner or Medium Cut Cleaner by hand only? If so, how did it work for you with the abrasives and cleaning? I know Meguiar's states that these are for use by machine only, but these products supposedly do exactly what I need for another car. I need something to remove etched hard water spots and coarse swirls/scratches.
Or, would I be better off using 3M PI-II Rubbing Compound by hand? It says it's recommended for use by hand. But, is it too aggressive, or more so than the Meguiar's Cleaners?
TIA,
MM
