If the drum head is plastic, try this: Get some regular two-part epoxy cement from the hardware store. Be sure to not get the quick-drying five-minute kind. Mix one part of each of the two epoxy components and one part concentrated acrylic paint. (You want the artist quality acrylic that comes in a tube, not the thinned-down crafter's stuff in squeeze bottles.) Mix 'em up and paint it on. Let it cure a couple of days before banging in it. It should be as tough as the plastic the head is made of. As always with anything experimental, test it on cheap junk first.
