waxing

I have a few questions on the best cleaning supplies for an E46. (Wax, soap, towels, etc.) Also does anyone know the best way to clear the fog off of my head lights? And in the picture attached is there any way to make the black plastic sidings on car and mirrors less faded? best way to restore...

Ok so I went online to search for the best car wax, and i found a company called Chemical Guys. I was wondering if anyone knows anything about them, if its worth buying any of their detail products
