The resin is rock hard and coarse sandpaper doesn’t do much at all! Anything else I could try? Thanks in advance August 15, 2018 at 8:57 pm #14982 Katherine SwiftKeymaster Hi Vina, Unfortunately, you cannot size a resin bracelet like you would a metal bracelet. Your best bet is to keep sanding. Author Posts Viewing 1 reply thread The topic ‘Can i manipulate hardened resin?’ is closed to new replies.
