Mike,
The label says "Rectorseal". I think that's the company that makes it.
There's a 5 inside a red circle. It says Slow Dry on the left of the
5 and Soft Set on the right. Pipe Thread Sealant is written under the 5.
I bought a 4 oz can at Lowe's.
Any brush-on pipe dope might work, but this doesn't harden and was
recommended for fittings in fuel lines.
Tom
