When you want to make older paint look really, really good a clay bar is a great tool. I just clayed the hood on my truck last night and I just dig this product. I can really notice the difference that the clay makes because my truck is white and that makes it easy to see the little specs and junk left behind even after washing. I have been using the QD from Mothers that came with the kit because for real QDing I prefer
Meguiars Final Inspection so I'll use up the bottle of Mothers for claying. In fact I like FI so much I bought a gallon of it this week.
The Mothers works just fine for claying but the trick is to find just the right balance between too wet (too much lube makes the clay slide over the contaminants without picking them up) and too dry (develops too much friction and gets grabby).
It's cool finding a new product that delivers on its promises. It's also cool adding new detailing methods to our own personal set of skills and knowledge base.
