Long term results of my Z6 test...
* At first, I was unimpressed. I used very little.
* Last Week or so, I did HALF my car right after wash. I used much more Z6, and felt I got a lot better coverage than before, the surface felt smoother, and the car was MAYBE a little glossier.
* A little while later, I noticed there seemed to be more dust on the non z6'd side.
* Recently, I noticed theres a LOT more dust on the non z6'd side.
