Just recently a member here posted a thread about teflon tape and pipe dope. I posted that I used to use LEAK LOCK before I retired from being a pipefitter/welder.
I got to thinking, I only brought one container from FL when I moved back to LA. and my cousin has almost used it all up. I contacted LL and asked where I could buy some local here in LA. They told me some local places and asked if my cousin and I would like some FREE samples. So, that's how I received them FREE in the mail.
