I used to have Mothers Caranuba, I hated how hard it was to buff out, then it just left dust all over the car. I recent;y used the turtlewax ICE synthetic (bought it a couple of months ago) and I love this stuff. I can apply it on the black panels and anywhere else on the car I want to. also, unlike the caranuba, it leaves a glass like finish every time I use it. I am one of those weirdos that has to wax the car every 2 weeks though and sometimes more frequently. 1 weeks at the least amount of time. I usually strip it before I wax it just so it doesn't hurt the paint.
