Floor Plate Screw Color Removal Question

[BRDHNTR]

Thanks Dean. Never heard of Flitz, I guess it's a polisher/cleaner. West Marine carries it locally. I'll try a little with a Q-tip on the screw heads. I appreciate the corrective work that Lawrence graciously did but just wish he'd have recognized that the color of the screws didn't match with the rest of the floor plate and cleaned them up before returning the gun to me. Like what the $#%&^!!
