TotalBoat Seal comes in 3 oz. tubes, and 10 oz. (290 mL) cartridges, which fit into most standard caulk guns. There are no special mechanical advantage requirements, or any other specific parameters when selecting a caulk gun to dispense Seal. It is helpful if the caulk gun has a seal puncture pin to poke a hole in the seal of the TotalBoat Seal cartridge.
