I just bought a used 96 Lumina and the paint is very good. I have a tube of Mequiar's scratch stuff and is this for the whole car or only for small sections? I normally would just get a Turtle wax white light rubbing compound. (Not the abrasive one!) Is that Mequiar's tube just another kind of rubbing compound? Will apply Kit wax or Zymoll after the Turtle or Meguiars. It is gonna look great as it already does after 12 years!
