A method of filling cavities with a hot melt adhesive composition. The adhesive composition comprises a block copoly(ester-amide) containing crystalline polyester and amorphous polyamide segments and a finely divided spheroidal metal. The weight ratio of poly(ester-amide) to metal is in the range of 70:30 to 30:70. The adhesive composition is applied as a hot melt to fill a cavity in a substrate and is sanded smooth to provide a surface which accepts paint.
