GG clay - what grade?

[glen e]

Is this stuff any good? I watched Mike's clay video and he speaks of several diff grades. What is the GG stuff? I used it today and my car is very clean, so there was very little "drag" on the clay....used ONR as lube....sound right?

I'd say it's a mild clay. Didn't notice any marring when I used it for winter prep and it was nice and soft.

I've read that some people think it's too soft when using it in the summer time but I haven't tried it in warmer weather as yet.

I did use the microwave trick and warm the clay for 25 secs - made it simpler to form into patties...thanks

I have the blue fine grade clay and i have found it to not mar the paint and it can remove quite a bit of build up.
