Hey sorry if this has been asked before. I have red seat gti and one whole side of the car is slightly faded due to it being parked in the same place for year. It needs a good cut and polish and to be honest I have never done it before. I have heard you can do damage if you don't know what your doing. Can I get an idea of recommended products and techniques. I'm trying to save a bit of coin so any help would be greatly appreciated.
