I've just used Sonus Gloss Shampoo by itself to wash the car. I previously used it once but after I washed with my regular shampoo, Meguiars Gold Class. Kind of like a second wash/quick detail. Anyhow, I noticed that the Sonus doesn't sud too well. Does this indicate a higher risk of scratching the paint? Also, after washing a few panels, my cotton washing mitt became very dirty. It was also quite difficult to rinse out the dirt stains. When I wash with Megs GC, my mitt stays pretty much clean throughout the whole wash. Did I just seriously mar up my paint? It's too dark to check now but I'm a little concerned.
