1. A method, comprising:
assembling a downhole tool,
the downhole tool comprises a first subcomponent and a second subcomponent;
the first subcomponent comprising a sealing element comprising a metallic or cured elastomeric material, an upper slip assembly, and an upper cone; then
applying an uncured elastomer liquid gel to an end of the sealing element of the first subcomponent;
coupling the first subcomponent to the second subcomponent;
the coupling causes the uncured elastomer liquid gel to at least partially fill each slot of a plurality of slots of a backup ring via coupling the second subcomponent of the downhole tool to the first subcomponent, the second subcomponent comprising a lower slip assembly, a lower cone, and
the backup ring;
the backup ring comprising:
a plurality of segments defined by the plurality of slots, wherein each segment is defined by a sequential pair of the plurality of slots; and then allowing the uncured elastomer liquid gel to cure into a solid.
