Rain Guards and Door Visors - Protecting Cars During Rains


Rain guards or door visors are often called as wind deflectors, thanks to multiple purposes they solve. While they are one of the cheaper accessories that get installed on cars, rain guards are highly underrated considering their wide practical usage. Before talking about advantages and disadvantages of rain guards or door visors, let’s first understand their types.


Rain guards can be of different types depending upon their mode of installation and look and feel. While there are in-channel rain guards that fir into the channels of the doors/windows (therefore called in-channel), more popular are stick-on rain guards that can be fixed/stuck on to the door frame with the help of 3M tape. While both work well, stick-ons are preferred due to their easy availability and variety. These days, even manufacturers themselves sell authorized rain guards for all their vehicles.


Apart from the type of installation, rain guards can be of different sizes, shapes and material. While rain guards can have a chrome finish, plastic-finish ones are generally preferred. They also come in different sizes, obviously depending upon cars, but depending upon their arch diameter as well. While some remain close to the car’s bodywork, there are others that stick out abruptly. It is however advised to go for the ones that remain closer to the car’s body since they do not pose an aerodynamic threat to the car.


Some of the advantages of rain guards are:


  • Rain guards don’t allow rain drops to fall inside the car’s cabin, therefore keeping the car dry.
  • They also work as side sun-visors.
  • With the rain guards installed, windows can be rolled slightly down for fresh air to seep in inside the cabin even when it rains.
  • With the rain guards on, one can keep the windows rolled down a bit during summers to prevent greenhouse effect and keep the car relatively cool.
  • They also act as wind deflectors thereby reducing wind noise inside the car when driving at high speeds.
  • Properly designed (manufacturer recommended) rain guards also aid in improving the aerodynamics of the car.
  • Rain guards can beautify a car’s exteriors as well.


Some of the disadvantages of rain guards are:


  • It needs some precision to paste stick-on rain guards as they are generally available in particular shapes for particular cars. Improper installation might not serve the intended purpose.
  • Poor design can not only ruin the car’s look and appeal, it can also hamper the dynamics of the vehicle.


While rain guards solve multiple purposes, they’re still not on the top priority when accessorizing cars. But keeping all the advantages in mind, they can be regarded as one of the most value-for-money (a set of 4 will cost around Rs.1,000-Rs.1,600 for most cars) and practical accessories.
