Who is this "we" of whom you speak?

Honestly, every plumber I know uses teflon tape. I know there's other
stuff available, and I'm sure it works, but were does this stuff come
from all of a sudden that "nobody used teflon tape"?

Hell, use old-fashioned pipe dope for that matter. It all works.

And another thing: what's the big deal about the "correct" tape for gas
(the yellow stuff)? Again, maybe it's better, but everywhere I go I see
white tape on joints in gas piping. And none of it leaks.

Sheesh.

I tried Rectorseal for the first time this week replacing my brittle
PVC greenhouse sprinkler system with galvanized and PEX. No leaks
first time and easier to apply than tape.
