I hope my posts about marring with the Sonus gray don't come across as bashing, as IMO that's like saying "hey, this H-T EC left micromarring!"...it's not a bash, just an observation that somebody might benefit from.
I *have* discussed this with DavidB (before I posted anything) as I was so concerned that I wondered if a bad batch of clay had slipped through. Nope, it was a deliberate reformulation designed to make the clay more effective at what it's made for, it's fairly aggressive clay.
If *I* commissioned a batch of clay, I'd have it made less aggressive, like the previous version..but I'm not in the detailing products business so I have to have a few different ones on hand to cover all the bases. Nothing inherently *wrong* with any of them, they're just different.
maesal-That's interesting about the A8, thanks for posting it! I've been leery of using this version of Sonus gray on our Audis for fear of marring. Interesting that it marred up my BMW so badly as I'm finding its clear to be about as hard as the Audis' :nixweiss Maybe small differences in hardness are enough to make *all* the difference.
I agree, it's best to use this stuff when you're gonna polish anyhow.
