Pro Tip: Don't try to use the Plumber's Putty you kept in your garage and is likely several years old and has long since dried out into a rock hard paper weight. Make a THIRD TRIP to your local Home Depot to get a cute l'il 9-ounce container for about $5 bucks. Yes, you will only need about ONE ounce of Plumber's Putty for this job and leaving 8 ounces - this time I was smart and used the extra to make a putty replica of Harambe the gorilla. Might as well be an amusing paper weight.
After this, I made the decision to replace the other sink's drain and strainer, as the entire thing was looking sketchy. This is where things went sideways. The strainer locknut was/is frozen solid to the drain insert stem underneath.
