On my second application of the Ultimate Quick Detailer (Black bottle) and it is fantastic. Water was still beading tremendously well when I washed the car...this is about 3 weeks after initial application. Second application definitely seemed to improve depth.

Do not confuse this with the regular QD that comes in the burgundy bottle. That IMO is very good but not great. Have not tried their NXT QD...hard to keep all these straight Meguiars! Why don't you just make 1 good product and stick with it?

 

^ NXT is awesome too. I put it on every time I wash my car now.

 

I stopped using the duster. I had washed the car, and a day later I used the duster + UQD to keep the car clean. After that, had a lot of scratches in the paint. I am pretty disappointed because I use clean microfibers every time I touch the car, and am very gentle. I think I can attribute the scratches to Nissan's sub-par paint too Ah well, from a couple feet away the car looks amazing! And the UQD is a stellar performer.
