OT - I believe so, it's the goop that predated plumbers tape. It's not an epoxy. Needless to say, read the particulars on the package.
A cheater bar, say three feet long, has proved immensely handy when plumbing chores need to be done. I got a 2"D pipe I slide over the pipe wrench handle.
Grunting while turning seems to help the recaliterant fixture turn loose. :-)
HHmmmm....the plumbers putty package doesn't say anything about a cure time.
I'm waiting a while to see if a leak develops.
So far, so good. Dare I try laundry tonight?
