ABSTRACT:
A method of filling a cavity in a substrate which comprises applying excess adhesive composition as a hot melt into the cavity, spreading the adhesive composition to fill the cavity, cooling the adhesive composition and sanding the composition to provide a surface even with the surrounding substrate. The adhesive composition comprises a block copolymer, aluminum powder and glass fiber. The block copolymer is selected from the group consisting of copolyesters, copolyamides, copoly(esteramides) and copoly(ether-esters) melting at a temperature above about 150.degree. C. and having from about 30 to about 70 weight percent of hard segments and from about 70 to about 30 weight percent of soft segments. The weight ratio of block copolymer to aluminum powder and glass fiber is in the range of about 3:7 to about 3:2, the weight ratio of block copolymer to glass fiber is at least about 2:1, and the weight ratio of glass fiber to aluminum powder is at least about 1:9.
