Rain-X Rain Repellent 500ml – Windscreen & Car Glass Water Repellent Spray

Rain-X Rain Repellent 500ml is a hydrophobic treatment for exterior automotive glass, designed to make rainwater bead and roll away from treated surfaces for clearer visibility in wet driving conditions.

Applied to a clean, dry windscreen, the Rain-X formula changes the way water behaves on the glass, encouraging droplets to form beads rather than spreading across the surface. This water-repellent effect helps maintain a clearer view of the road when driving in rain and poor weather.

The protective treatment also helps make frost, ice, salt, mud and insect residue easier to remove from treated glass, providing useful year-round windscreen protection.

This 500ml version comes in a convenient spray bottle for controlled application and provides a larger quantity for repeat treatments or use across multiple suitable exterior glass surfaces.

Important: Do not use on plastic surfaces such as motorcycle visors or Plexiglas.
