Been using Jescar Power lock plus over a ceramic sealer for awhile on my old Toyota. Granted, the paint is 22yrs old. I'm not expecting miracles here. And the car was outdoors it's entire life. Found the Jescar's works well, on my particular application, for about a month. Did some research, found that if I use Collinite 845 over the Jescar, it will extend the " beading" life / UV protection, etc. The Jescar's does leave a fantastic shine. Easy on, easy off. Haven't tried the Collinite 845 yet. Waiting on it's delivery. Heard nothing but good things about using these 2 in combo. Allegedly, it lasts 6-9 months. We'll see.
