Fred, I just arrived home after a 6-day absence.
Wehehell, sal, the 215 as the others said is an extremely good AIO. I did a Heather Mist Accord (the same as Corey Bit Spank's) with it and the highly unqualified eyes of the owner popped out, and he said wow, this looks much better than the previous combo on it (Z2Pro/Z8), because the paint looks more silverish now instead of the golden hue of the Zaino.
Alone it will give 2-3.5 months of protection which is very good from an AIO.
The 216 is a bit like the 1000P in its optical characteristics. It can be a bit flat initially on some darks, but as it cures it will look significantly better.
The 217 is like VM, although I haven't got enough experience with it to say more. Tdekany used it more extensively.
I love the look of 2180 too, and yes, it needs the special layering to perform. Temperamental product. If you like a warmer hue, you'll like the 218, which cleans a *bit* more too.
Finally I think the 425, 108, 1000P, the Pink don't need introduction.
I was quite disappointed with their soap, because its lubricity was on the low side, but again the cleaning power is awesome. The 303 works very well with a machine, as it is functionally abrasive.
