Nice video and I agree with all that was said. A couple months ago there was a similar thread here and I said this:
"What an idiot I am! Yesterday I tried Sonax S+S and did it all wrong. I read the instructions, saw the video and read this thread and still did it wrong. I washed my car as usual and rinsed off. Before drying I sprayed on S+S in small areas such as half the hood, the trunk, a door panel, etc. But instead of rinsing it off I skipped that step for a reason that only a higher wisdom knows and went right to drying, using the product basically as I would AquaWax or any other drying aid. Big mistake. Huge mistake! When I finished I looked at the finish from all angles and sure enough, I saw haze on the finish. I needed a QD to work it all out. Not in all areas but there were enough that had haze on them that it doubled my work. I swore I would never use this pos again.
Today I remembered what I did and that it was all wrong so I started all over and washed the car again. This time I did it right and gave a good rinse off of the product before drying the car. What a difference! It had a nice shine to it and only took ten minutes to seal the whole thing, a piece of cake! And no haze whatsoever. I'm nearly 70 years old and this happens now and then so don't make fun of me because it will happen to you guys too some day - and I guarantee that. Anyway, S+S is a good product and does all it claims. I will use it again. Just follow the directions!!"
