A seal for attenuating energy from an electrical discharge across an interface may include a cover defining an inner volume containing a filled sealant including a semi-rigid sealant mixed with a filler having a multiplicity of discrete particles of different composition than the semi-rigid sealant such that the filled sealant is adjacent the interface when the cover is placed over said interface. A method for sealing an interface may include forming a cover defining an inner volume shaped to enclose the interface, forming a filled sealant including a semi-rigid sealant mixed with a filler having a multiplicity of discrete particles of different composition than said semi-rigid sealant, placing the filled sealant within said inner volume and placing the cover containing the filled sealant over the interface such that the filled sealant is adjacent the interface.
