I had already bought a $15 tube of silicone grease when I got my silicone seals. Today I was at Lowe's and needed some plumbers grease because I was out on my work truck and my new tube was at home. So I looked by the thread sealant and there it was - Plumbers Silicone grease. It used to be simply Plumbers grease but now it's Silicone. So I bought the nice sized container and went to fix a faucet. Upon using the grease it was a lot heavier bodied than the grease I had already bought. I like it much better. The best thing was it only cost $3.50
