At Nanotech Surface Solutions, we are aware of the dangers rain poses to drivers each time it happens, which is why we offer an SiO2-based, invisible, and long-lasting protective coating for windshields: Rain Shield. A single application lasts up to six months, making it extremely convenient for DIY enthusiasts to apply it themselves and start enjoying the benefits of increased visibility during rainy days immediately. Rain Shield is very affordable and easy to apply, why? It's simple, we don't believe drivers should be risking their safety at any time. 

Increase Visibility & Safety During Rainy Days!

Rain Shield is a long-lasting, SiO2-based protective coating that creates water repellent properties on windshields, rear windows and side windows, which increase visibility and safety during rainy days. Rain Shield helps remove sleet and snow and also makes it easier to clean bug splatters and bird droppings. It makes rain drops slide off when driving over 40 mph without having to turn the windshield wipers on. Even though this coating provides exceptional rain repellent properties, windshield wipers should still be used as frequently as necessary.

Each 0.33 ounce sprayer bottle has enough product to coat a sedan, pick-up truck, or SUV's entire windshield for up to 6 months.

Some of its benefits include:

  • Increases visibility & safety during rainy days.
  • One single application lasts up to 6 months.
  • Easy to apply.
  • Very affordable.
  • Completely invisible.
  • Does not leave a film or greasy residue.
  • Can be used on windshields, rear windows, & side windows.
  • No constant reapplication needed.
  • Makes it easier to clean sleet & snow.
  • Makes it easier to clean bug splatters.
  • Performance not affected by windshield wipers.


1. How long does Rain Shield last?

A single application of Rain Shield 0.33 Oz. (10 ml.) will offer rain repellent protection for 6 months on average considering frequent driving and windshield wiper use. Rain Shield will also make it easier to remove sleet and snow (during winter) as well as bug splatters. 

2. How is Rain Shield different from Rain-X and how does it work? 

Rain Shield is not a superficial coating and will not wear off after 2-3 weeks. Due to its nanotechnology formulation, Rain Shield is able to bond on a molecular level to the glass substrate sealing its micro pores and crevasses and creating a super-hydrophobic surface. 

3. How much can 0.33 (10 ml.) ounces cover?

This is enough to coat the entire windshield of any sedan, SUV, or pick up truck.
