Accumulator-- I used the Nanoskin Sponge (fine) this year with UWW+(mixed at waterless wash dilution) as a lube. As others have mentioned I soaked the sponge in the solution for a few minutes then sprayed copious amounts on the paint before applying the sponge to the paint. After small sections it's simple to hit the sponge surface with a hard spray from the hose so it cleans it off very well, then dip in the UWW+ solution, spray and begin on the next section. Really moves along much faster than clay and I couldn't find any marring afterwards with a couple different light sources. All this was done after IronX ofcourse. I was going to give the paint a light polish afterwards, but I took extra care just to see if I could decontaminate without inducing marring.
