Body putty ?

[chevymaher]

I don't need a serial number on stuff that isn't seen. So I kinda go with the flow on hidden things.

Plumbers putty is the same stuff. Comes in a tub at lowes. It is for sealing the sink drain into the basin.

Slightly different color and I am sure its molecular structure is a electron off or something. Just don't let a purist know it is there so he doesn't faint and go into a coma.
