You can buy a lot better waxes then there Butter Wet Wax! I would advise you get Clearkotes Carnuba Wax.
Most of the decent Chemical Guys products are already out there in the form of "other brands". All the labels tends to be poorly written, i have some fun ones where it says "no polishing or cleaning action" then a few lines later "the gentle cleaning action restores the paintwork....". Complete tripe!
Claims that shampoos can do the same job as a "paintwork cleaner" (ie. a polish which is only chemically abrasive) i dont think so....
I think they really believe that b/c they are cheap, you can forgive them....and maybe you can?
All in all there a few good shampoos, GlossWerks being the best. All of the QDs under there own lable are pretty average. Some of the pads get good reviews, IMO they wont last as well as your flat Lake Countries or Meguiars Soft buff 2.0's.
I have tried there latest polishes, there OK. Menzerna still seems to turn a better result.
Petes 53 is a nice wax is 50/50 and the XXX is good for the money.
