Cut through CC?

I know I could have put this in the Machine Polishing sec. but it seems nothing ever gets answered there.


Anyways just a quick question, I know you can burn through CC (clear coat) with a machine, but not a PC or (I think?) Griot's Garage polisher. But what if you are detailing a car that has thin CC and you use an abrasive compound or polish, couldn't you "cut through" the CC? Even with a PC or GG?


 
 
Enough time and an aggressive enough compound can do it.  Particularly on edges.  It is definitely possible but far less likely with a DA than a rotary.  


 


Today I had someone observing me to learn as I finished a major correction on a 7 year old black car.  The car has heavy road rash on the front clip and the rockers so correction on those areas was limited.  He commented that, had he been working on his own car, he probably would have tried to remove more of the road rash and heavy marring.  He could very easily have gone through the CC on the various edges if he had attempted to do so.  


 


It is a good lesson:  <span style="color:#000080;">It is just as important to know what not to do as it is to know what to do and how to do it.
 
AquaHawk- Yeah, any time you do abrasive work you risk taking off too much clear.  It could even be done by hand.


 


The only time I truly cut through I was using a PC and a mild combo, I never did it with a rotary, when wetsanding, etc. etc.


 


And note that it's not just a matter of cutting through the clear; if you thin it too much you'll render it susceptible to UV damage and premature failure.  According to some sources, it doesn't take all that much thinning to cause problems.
 
A PC can level defects therefore it can level paint. I would avoid heat, staying in 1 place for a long time, heavy pressure and edges.
