Blackthornone- That's interesting about your experiences with the Mother's, how it was so completely different from mine. I too wonder if they changed it :think:
When I compared Mother's to Griot's it was a straight back-to-back comparison, both clays in hand, and I simply couldn't tell any difference. I can't remember when this was, but it was post-2000 as I was in my current house/shop at the time.
When Griot's changed theirs from green to yellow (maybe around '95 or so

), all that changed was the color..the clay behaved the same as best I could tell. But other clays *have* changed significantly over the years. Maybe the Mother's changed as well...too bad
Forrest isn't posting here these days as we could just ask him for the straight scoop.
Are you using SpeedShine for lube with the Griot's clay? What did you use for lube with the Mother's?
