I wish I would have snapped some before and afters of my first ONR use, but I didn't have the time. My car was pretty dirty as it had rained heavily the day before I used it.
I mixed up a sprayer with the QD strength, plus mixed up a sprayer at double QD strength. I was paranoid about the really dirty bottom panels, and figured I'd rather waste a little more product than mar the paint.
I used a single bucket with 2oz of ONR, and a chenille sponge. I found that the sponge floated on the top, and the dirt was pulled down to the bottom, keeping the sponge crud free.
I went slow, and did relatively small portions at a time. The black paint was sparkling and deep looking. I looked at panels with a xenon light, and there was zero swirls. I did miss a few places when drying, but went over them with the QD and a MF, and they came right out. I have to say I was very happy with the results, and surprised too because I was a skeptic.
