    No, you can only do that afterwards, by using masking tape to cover what you want left polished. Then re-dull the exposed parts with a dry glass brush, or a light touch with a fine frosting wheel.

    Once the masking tape has been peeled off, you might also have to remove slight sticky residues with a cotton bud and a solvent such as acetone.
