What type of treatment is Rain-X used for?

Rain-X is specifically formulated for application on windshields and other glass surfaces to enhance visibility during rain. It works by creating a hydrophobic barrier on the glass, causing water to bead up and roll off, which helps improve driving safety in wet conditions. This treatment not only improves visibility but also reduces the need for wipers to be used as frequently, as rainwater is effectively repelled.

This makes it highly effective for maintaining clarity and safety on windshields, particularly during adverse weather. The other options—wheels, paint, and upholstery—do not utilize Rain-X, as they each require different types of care and treatments tailored to their specific materials and needs.
