My wife’s 2009 red Honda Fit is suffering from some extremely faded paint. Painted metal surfaces have faded to a pinkish red while plastic surfaces have maintained most of the factory red. I washed/clayed/and began polishing with a fairly aggressive Sonax Perfect Finish and a Chemical Guys orange hex pad. The paint is becoming shinier but the red color is not coming back. Do I need to use a more aggressive polish or pad or is it possible the paint became so faded that I will not be able to bring the color back? Thank you for your input.
