I don't want to come off wrong, but I'd like to put my 2 cents in about clay bars. I bought the Mequiers package and tried it on the new Challenger. One spot, about 1 ft. square. Didn't notice a licks bit of difference from the rest of the car. I also tried 1 side of my Harley tank, and a small area on my wifes 75 Mini Cooper. Did not find any improvements in either case. I know some of the members swear by clay bars. But I just think I've been ripped off for $20. A good wash followed by carnuba wax works fine. As I said, this is just my opinion but spending a whole day for questionable improvement doesn't justify the effort.
Okay, here is my 2 cents. Clay bars are going to work on paint that is older. These Challenger cars at just too new. Depending on the environmental abuse you give your car, you should probably use a clay bar if your car is around 3 years old or so. My wife's 2002 F150 Supercrew finally needed it after 6 years but we always keep it in the garage.
I did the clay bar procedure which took all of the environemental crude which you can't wash off and you can feel how smooth the paint is by running your hand across it.
If you run you hand across your hood after washing it and it still feels gritty then you need to use a clay bar. If not, then don't waste your $20.00.
I have been a big fan of NXT polymer wax for the last several years after Meguiar's quite making the commercial version from our dealership. You can get NXT at Walmart.
I have been using it now for about 4 years. When I put NXT after the clay bar procedure, you hand just slides over the paint. As for carnuba, it is a nice product but it doesn't last as long as a polymer especially when a car gets abused by the sun.
