what causes condensation to build up in my garage? I live in midwest &
weather isn't extreme. The garage is not insulated or heated. I am tired
of the rust on my tools. anyone know how to cure it?

Temperature differential and moist air. The garage is probably cooler than
the outside air right now. You bring in the warm outside air, close the
door and the moisture condenses. Leave the door open longer or heat the
garage a bit.

Or use an exhaust fan with a differential humidistat.
