i detailed an 03 toy seq. 5 and a half months ago. its white and it was horrible. oxidized filthy and no shine at all. I polished/compounded with m105 and a tang hyrdo pad then applied the sealant. just detailed it again and while it was nasty again it washed pretty dang clean and then dg 501 with a white ccs pad and its gleaming. thanks 3.0 you saved me a lot of time
