Great question from an expert like you.....
not sure.....I guess would depend on the type of auto.......like an "Aaron Judge" doesn't look too hard.....Pujols....ect....
I would say a day or so??? maybe after a few months you wouldn't be able to tell the difference???
a true artist or someone with any talent could probably perfect it in a few hours I would assume(you know what it means to assume)
id love to hear from an auto forger!! how easy it is I'm sure
