Hi all. Newbie here. Must say this site is addictive and have learned so much. However, at this point have more questions than answers. Here is one. 02 white Camry that has been neglected but looking to correct that. Have decided on the XMT compound/polish series, claying, etc.....but my question is I am sure a subjective one, but how do you assess the current paint condition and decide what level of correction to start with? As this site emphasizes, the least amount of aggression to correct the problem. But how does one know just where that is? My best guess at this point is XMT #3 and work from there. Feed back please Thank you in advance.
