I think he's referring to silicone gasket sealer. I'm very familiar with two products from the Chrysler dealer. The gray stuff gets harder and will seal and bond even if there's some oil residue on the surfaces. That's good for oil and transmission pans. The black stuff stays more rubbery and will not bond through any oil residue. Either one will seal out moisture and hold the broken plug together. You'll be able to pull it apart easily the next time if you have to, and you can peel off the sealant.
I'm sure other dealers and auto parts stores have the same kinds of sealers with their own names on the tubes, but it's the Chrysler ones I'm familiar with. You might even ask at any dealership, if you can find a mechanic to talk with, if he has an almost-empty tube he will give you so you don't have to buy one. Once the tubes are opened, the stuff cures on its own after a few months so it's not something you want sitting around for those "just in case" moments. I use this stuff all the time to hold things together. If even works well for sealing arcing high voltage transformers in picture tube-type tvs!
