If left in the damp shed, the old bicycle will rust out before spring.

By the time we returned to the coastal town, the old pier’s railing had rusted out and collapsed into the water.

If the old gate rusts out, we'll have to replace it next spring.

The rusted-out bicycle leaned against the alley wall, its chain frozen and the tires collapsed to nothing.

The old pickup is rusting out in the driveway, and I worry it won't start this winter.
