Pipe Thread Sealant?

[mfinn]

if I were to use the PLASTO-JOINT STIK for a submersible application in my tank, would it "leach" chemicals?
It would be a very small amount, just to secure two 1" bulkheads.

There are a lot of people in the hobby who use it and I haven't seen any reported issue, or have seen any issue in any of my tanks.
