His powder had attempted to form a glossy fillet between frame and head set race. It is glossily jagged and possibly prone to chipping.
Smoothing the high spots with an abrasive will decrease the possibility of chipping.
A light filing at a close to flush angle will hardly be visible, if at all.
At least, I never examine headset race to head tube seams to assess the glossiness of the juncture...
And, powder IS polishable.
But, the OP is free to take or leave my advice as he sees or is persuaded to see fit, and it will not upset me one bit...........
