Mav, I know yer not picking at me. And my thoughts are the same as yours. Why are some people reporting problems when my experience has been very positive?
Could there be an interaction between previous treatments used on the cladding and R/R? I definitely could imagine some chipping if the cladding had been painted or clearcoated. R/R is not for painted surfaces (sorry Riff, hood inset R/R treatment was prolly not a good idea, tho i used it on mine once, with "meh" results). It is a penetrating solvent after all. It could possibly weaken paint or even dyed surfaces if the solvents used are unfreindly with eachother.
Of course my experience is only mine, I cannot speak for others and more input is definitely appreciated.
Oh, and my description of what it does was not lifted from the bottle, it was my own personal observation of how the substance interacts with the plastic.
