"PRC", or Products Research Corp., came up with a line of two part sealants many years ago. There are far too many to describe here. Aircraft Spruce sells only one type and that is "ProSeal 890 Class B-2". 890 is a general purpose sealant for fuel (gasoline), pressurization and faying laps. There are specific types available from API and others for windows, kerosene, aviation gasoline, etc. Class B is thick and class A is not so thick. The dash is 1/2, 1, or 2 and that is the working time in hours. I recently made my outflow bucket gasket by doing a "PRC" release on the bucket flange to have a built in seal. It worked as well as any micro release. The contents are polysulfide polymer and phenolic resin powder with calcium carbonate and toluene. SemaKit makes a less expensive variety now the patent has run out. Try it... you'll like it.
