".006"
Most likely the Decks were machined 0.006" clean up would be my guess.
I would use a Paint remover (DOT 3 brake fluid or commercial paint remover) and a plastic bristle brush to remove the paint from the pad, just be careful to min mess and resist the temptation to use any scraper, blades, power wire wheels etc. Be gentle and take your time, No sandpaper, No scrapers, No razor blades. It can be done.
