A damaged drum, or at least a damaged portion thereof, is heated until it reaches a softened state and is then drawn over a template, or mold, having the substantially the same shape and size of an undamaged drum. The drum is allowed to cool sufficiently to return to its hardened state, whereby it substantially assumes the shape of the template. The refurbished drum is then removed from the template and is essentially ready to be used again.
