Only a modeler ...
... would make a special trip and drive 10 miles to an electronics supply store in the nearest big town on his day off to buy a roll of 0.031-inch rosin core solder, not because he needed it for a delicate electronics project, but because he knew it'd be perfect for the cockpit rub rail on his 1/72 Sopwith Camel.
Now ... what am I going to do with the other 10 feet of this stuff?
