My first time using Z products and worth every single penny. Questions to those Z Pros:
1- Is the Clay bar reusable?
2- I used one Z2/Z5 applicator, can I just wash it and reuse it again?
3- Didn't have a good day here in NY to do it sunshine had cloudly/light rain when I did it. I still have the last coat of ZFX on it and it got wet from the rain, am I supposed to let it dry or just buff it off?
4- Is the buffing machine necessary to use at all for Z products?
