I got the tube, punctured the seal, cut off the end of the nozzle and nothiing came out. Checked that the seal was indeed punctured, cut off more of the end of the nozzle and nothing again. Cut off more of the nozzle and squeezed like crazy. The silicone came oozing out of the bottom seal. What a mess.
