Well, I finally placed my order last night from Adam's. I bought the Porter Cable as well as the butter wax, clay bar, detail spray, brilliant glaze, revive polish, scratch remover, applicator pads and microfiber towels. I was just going to get the Absolute Essentials kit, but I ended up paying about $60 less and I didnt really need the other stuff that was included in the kit, and it was my rationalizing with myself that I am buying new cleaning supplies when I just bought a ton of stuff a couple months ago. I just had to try Adam's stuff after seeing EFI-1's work and since they have the 20% off going on, I figured the timing was right. I cant wait to use it on my Z.
