LA-CO42014 Slic-Tite Premium Thread Sealant Paste with PTFE, -50 to 500 Degree F Temperature, 1 gallon

My pvc sewer pipe threaded access point is leaking. will using this seal off the access point indefinitely or still allow access?

Would this be good to utilize on an oil drain plug before reinstalling during automotive oil changes?

How to revive old dried out slic-tite, is it water soluble?

Can someone check the back label, does it have ingredients list? Specifically, would like to know if there is silicone in it.
