I have both, just put CQ on the gf's black car for my first use, and after doing the prep work, used a little round make up remover like CEE DOG used in his testing, well, the car was "sqeeky" clean and the applicator was not totally primed and it marred the hood. I tossed those and used the cotton applicator that came with the CQ and did the rest of the car. Last night I rebuffed the hood to remove the CQ and the marring and after polishing and stripping the hood, I reapplied CQ. I found once I got a feel for applying it, waiting around 15 minutes and going back over it with a MF, it was not bad at all and I REALLY LIKE IT! Next up will be my black car and I will use the OC so I can compare the two...
