thanks bro so pretty much if i have a ball with a black signature or a perminate marker sig i am screwed so jw would going over the black signature with a blue pen hurt the sig at all except for the fact that it would not qoute un qoute be from the player anymore

i wouldn't trace over it, from what i read there are a few (not guaranteed) procedures to restore the auto's but i would be hesitant unless its an au i could afford to loose.
As for blue ink, i have a 1956 Yankee team signed ball in blue ink & looks great. It doesn't get much exposure to light which helped keep it that way. Heres a pic from 2 of the au's.
