*MY* experience has been that *GENTLE* claying does NOT remove an appreciable amount of wax or sealant. I spot-clay all the time, with almost every wash, and my SG still lasts over 8 months, even on the areas that get clayed all the time, and my other forms of protection all last many months also. As long as I'm very gentle about it (and that's the key), it just doesn't remove it. It's not like I wouldn't notice, so I just

this idea that claying removes protection. Not intending to be argumentative, but I just don't understand... DOES it remove OTHER PEOPLE'S protection? If so, then THOSE experiences/observations and conclusions would be just as valid as mine.
Examples of my experiences:
The last time Accumulatorette took a long summer roadtrip in her A8 it came back with a LOT of bugs on the leading surfaces. I clayed them off while washing and the wax (3M Showcar paste) was beading and shining just as it did before she left.
The rocker panels and areas behind the wheels of our MPV get clayed all the time (tar, etc.) yet they kept beading (and looking great) for a *YEAR* after the last time I applied (multiple coats of) SG and Meguiar's #16. I've since clayed it several MORE times, still doesn't need rewaxed.
Perhaps my experiences are unique, but *I* have no reason to believe that clay strips protection. :nixweiss
