Claim:
1. A gasket for placement between a generally flat or slightly curved upper surface of a static base of an aircraft structure and a generally flat or slightly curved underside of a removable workpiece, the upper surface of the base and the underside of the workpiece being generally conforming surfaces, the workpiece for removable attachment to the base of the aircraft structure through a multiplicity of fasteners, wherein the underside of the workpiece and the upper surface of the base are generally conforming in their planes, the gasket comprising: a cured voidless elastomeric gel body, the body in the uncompressed state with a multiplicity of fastener holes therethrough the body being generally tabular with an all flat, non-configured lower surface and an upper surface and side walls defining a perimeter, the perimeter of the body generally conforming to the perimeter of the workpiece, the body having a thickness of between about 10 mil and 50 mil, as measured between the flat lower surface and a highest point of the upper surface, the upper surface configured with one or more high portions and one or more low portions, the low portions being areas of minimum thickness, the gel of the gel body flowable between the high portions and the low portions responsive to fasteners urging the workpiece towards the base as they are torqued to a preselected torque value, the upper surface of the voidless body capable of conforming to the shape of the underside of the workpiece and remaining free of voids in a compressed state; and a skeleton member disposed between the upper surface and the lower surface.
