OK, clay is an abrassive. It does not "lift" contaminants off the surface of paint. It "sands" them off. Clay works. I don't doubt that at all. But if you have a lot off "junk" on the paint's surface wouldn't it be removed more easily with a good polish #80 or #83 and a pc or rotary buffer?
Another question. Because clay "sands off" the contaminants what do you do with particles that are actually imbedded in the paint surface, ie. rail dust filings or manufacturing pollutants?
