Done *CORRECTLY*, claying should not cause damage to automotive paint. The fact that someone DID apparently cause marring (or other problems) by claying should NOT be used as a reason to denigrate claying in general terms. There have been maybe a dozen people on this board who have apparently damaged their paint while claying, a VERY small percentage of the Autopians who clay their vehicles.
The red "overspray" clay is a different animal entirely, but as simon97jetta said, the marring from THAT stuff isn't all that bad either and should polish out just like minor swirl marks.
Clay DOES get contaminated, that's because it picks up the contaminants that are on/in the paint. And those contaminants CAN damage paint if they are rubbed against it. Some people fold it over to "lock in" the contaminants, others pitch it and get a new piece (best method, IMO). Clay is a renewable resource, paint is not. I would NEVER hesitate to "go through a lot of" clay.
Without clay (or "ABC", I use both), how can you get ferrous contaminants out of your paint? Polishes do NOT do this, at least not completely. Anyone who has been stuck with permanent "rust blooms" from "rail dust" knows that it pays to remove that stuff before it starts to oxidize.
It seems to ME that Pinnacle's clay is more often associated with "clay marring problems" than some other brands. Just an observation...not a slam at the stuff.
And yes, AIO is a GREAT cleaner for removing clay residue, not that there should really BE any residue to remove anyhow!
DefBringer- Heh heh, none of the above are of any real help to you, though, huh? Sorry you have the problem, but I wouldn't be to hard on yourself about it.
To *ME*, like Cujo31, the problem looks more like something that the clay UNCOVERED and/or made more obvious than something that the clay itself DID. Either way, if it does NOT come out with something like DACP, then yeah, you have a real paint problem, maybe one that needs a paint gun to fix. But you won't know until you polish (or even compound) the area.
Hey, if it gives you the incentive to get a PC, go for it! Yes, a PC is VERY safe and easy to use, even on black.
