I do not know what it is, but in some places that I have dealt with Gun Gum, can the Gun Gum after a few days by dry pull with your fingernail and peel. In other places, however, it holds, of course, everything has been previously sanded blank. At another point, the final pot is leaking and dripping condensation out there always. I sanded the place, made warm and lubricate the paste on it. Allow to dry at least 96 hours and does not find it tightly. The water makes the Gun Gum soft and it drips out further. Too bad. Thermo Steel or Quiksteel I'll try next.
