It has little holes with red felt bushings which the stickers protrude through. Each hole has some white powder (which smells and looks like talcum) dusted in and around it. I don't specifically see any white powder anywhere else, but I theorized that it could have gotten into the hammer butt flange bushings making them sluggish. I have used Protek CLP in eliminating sluggish flanges with great success, but my specific concern was whether the talcum powder (if it IS talcum powder) in combination with CLP might make things worse! (After all, if you can mix water and flour and get paste, it's possible in my mind that CLP plus talcum powder could make portland cement!) Tom Sivak
