What is this gunky stuff?
I pulled out my refrigerator
to resurface the shelf it sits on. Then I pried up some old sealant material that was affixed around the black water tank vent pipe, and the hole that my gas line comes through, and the crevice between the shelf and the surrounding walls. I think I should buy new putty and replace it before sliding my refrigerator
back in. But what exactly is it? I see "plumber's putty" on the internet. Is that what I should buy?
