Gum and wax removal is minimal David. I'm talking about any process that will add grading points to a card. That's a whole different thing. There are people who build corners, who glue the fronts and backs of two different cards together and then submit them and get high numerical grades. Some of these alterations are caught by the graders, but many of them are missed too. That would concern me greatly if I were buying expensive high grade cards ( I don't).
