Hey everyone! This is actually my first time posting here, but I've been on and looking at the forums for a while now. Great(The best) car care site that I know of! :up Anyways, I am getting ready to wax my car with some P21S that I recently bought(I bought the kit), and have a few quick questions...Should I use some Dawn to wash the car first? I know most people recommend it, but I didnt see anyhting specifically in the instructions to use Dawn to strip the wax first before applying the P21S. So, I wasnt sure if P21S have different processes for their wax. Also, would you recommend using a clay bar with this? The car is a 2002 Subaru WRX, and this will actually be its first "real" wax, excluding the quick spray on waxes and sometimes at the car wash. Thanks a lot!!
