A balanced aluminum driveshaft includes a driveshaft, which is adapted to rotate in service about an axis therethrough but which is unbalanced relative to rotation about the axis, and a balancing composition for balancing the driveshaft. The balancing composition includes a polymer carrier of an adhesive composition which is cured by the application of ultraviolet light and a particulate material having a density higher than the adhesive composition dispersed therein. The particulate material includes metal particles having a particle size in the range of 0.080 to 0.120 inches and comprising 90% to 94% of said balancing composition by weight. Predetermined amounts of the balancing composition are adhered at selected locations on the outer surface of the driveshaft to balance the article for rotation about the axis.
