Charlie BarokasAdding and Removing is deemed out of bounds by every major grading company. It is a very slippery slope to say that it is ok to do this or that but not this but maybe that. Its much easier to say don't add and don't remove from a card and draw the line. Soaking T206's from old photo albums seems to be a different story.
But in this case someone desribed getting a PSA 6 MK into a straight 6, unless everybody believes in magic, the card was altered.
I think that disclosure is the key, if you plan on using a paper conservator to improve a card that you have no intention of grading to resell and plan to disclose the fact if you ever do sell the card, then fine. But adding or removing to improve the card inorder to regrade it to ascertain a higher grade only to sell it for a profit seems to be out of bounds.
