Wow! That's one heck of a purchase!!! You're gonna love everything too. Feel free to reach out if you have any questions. I'll try to give you a quick rundown on some of the products:
Cut - I like using it with a Microfiber cutting pad via DA most of the time.
Polish - following Cut, I tend to use a Black B&S foam pad
Speed - I like using it for quick 1-steps where you want a decent amount of cut and a great finish - Green B&S foam pad usually does the trick. This product leaves behind some decent protection, but you can also top it with Express or Poxy.
Poxy - Red B&S foam pad and apply it super thin. 10-14 small drops will treat an entire car.
UNO - This product can be used with any and all pads. If you start with a cutting, swap to a finishing after. 1 product does most things by just switching pads.
Adapt - Key is to find the right pad (I like MF finishing and Green)
Again, hope this makes sense. If not let me know.
