I've never been a fan of the claying process. I have black metallic car and although the clay makes the paint feel incredible, I will occasionally leave waxy clay streaks by accident even if I'm lubricating considerably. They can be buffed out, but it is time-consuming. My car is now due for a claying again and I've noticed there are all these new clay products out there like mitts, towels, and speed clay. I'm sure they all do the job in varying degrees, but I'm hoping someone who has "been there" could let me know what they've found as best? Any recommendation on one of the newer clay products?
