The present invention is a method of using a sealant material, which includes providing the sealant material, where the sealant material comprises mineral oil, petroleum wax, and a viscosity builder, and where the sealant material exhibits a first hardness. The viscosity builder is selected from a group consisting of polybutene, a styrene-rubber diblock copolymer, an ethylene-propylene oligomer, and combinations thereof. The method also includes applying a shear force to at least a first portion of the sealant material, where the first portion of the sealant material exhibits a second hardness after the shear force is applied, and where the first hardness is at least two times greater than the second hardness. |
