I found dusting it on the joints/rivet lines and buffing with the microfibre was enough to remove the residue.
Take a piece of an old cotton shirt (thin enough to be slightly porous), put a spoonful of cornstarch in the middle, then pull the edges up and wrap an elastic band around to make a powder puff. Dab the puff along the rivet lines and skin seams, it will leave a trail of powder. Then buff with the microfibre.
