On Guard Detection Paint changes color to alert you to the presence of acids; including both liquids and gases. On Guard paint reverses to its normal color automatically after the leak has been isolated, repaired, and flushed with water — no need to repaint the affected area. This paint is designed to be applied and maintained just like any other quality exterior paint formula. Paint dries to the touch in 30 minutes, can be handled in 1 to 2 hours, and recoated in 12 to 24 hours.
