An assembly for use in a downhole tool. The assembly may include a body that includes a chamber with a solder suspension contained therein, the solder suspension comprising solder particles, each solder particle comprising an outer shell and a liquid metal core that is exposed and solidifies upon rupture of the outer shell. The assembly may also include a port that allows fluid flow between the chamber and an area outside of the chamber. The assembly may further include a plunger actuatable to apply a force to create a pressure to the solder suspension within the chamber to eject the solder suspension from the port at a velocity to rupture the outer shells of the particles upon contact with a surface.
