Malachi- Nah, I'd rather discuss this one right out in the open. Given my direct discussions with DavidB about the current version of Sonus gray I'm utterly confident that there's nothing out of line with this thread and my observations about how it behaved for me seem relevant to the original poster's topic; he and I had identical experiences.
And you don't sound a bit holier-than-thou to me
I think it's just risky to compare seemingly similar clays (though I'm the guy who says Mother's and Griot's are the same). If the Meg's works OK for you then I'd stick with it. then if you need something with special characteristics (milder so it won't strip LSP, stronger to remove something tenacious), you can always get something different that's just right for that job- and for those times I'd go with the two Sonus clays.
I think what happened with the Sonus gray on the M3 was that I assumed (always risky, that
) that it would be like all the other clays I've used, specifically, like the previous version of Sonus gray. Plus, this car had never been clayed in its ten years, so I was admittedly being somewhat aggressive. The combination of more aggressive clay, more aggressive use, unknown paint, and *NOT CHECKING MY WORK PROPERLY* added up to a lot of marring. Not severe marring by any means, came right out, but still it's something I hadn't experienced before. I immediately put an end to using that clay on the vehicles I'm doing these days and have since used it (with great results) on the back sides of some wheels. I wouldn't hesitate to use it on a vehicle that needed it and was gonna get polished anyhow. But if I didn't want to risk the marring I'd use another clay instead.
Note that since I did *not* get marring on every bit of paint that I clayed, it must be possible to clay with the Sonus gray without marring (at least on hard paint). But you can't just no-brainer it the way you can with so many clays...noting that my definition of "no brainer" is probably quite different from some people's
