Is it necessary to install rain guards on a car?

[VonVivienne]

Whether it is necessary to install rain guards on a car depends on the frequency of rain in the owner's region. If the area experiences frequent rainfall, it is recommended that the owner install rain guards. The primary benefit of installing rain guards is to prevent rainwater from splashing into the car during rain. Although the window can only be opened slightly, it ensures air circulation inside the car during rain, maintaining fresh air inside. Additionally, rain guards provide some shade, avoiding strong side sunlight that could affect driving visibility. When installing rain guards, it is essential to consider their quality, which can be evaluated from two aspects: the material of the rain guards and their adhesive strength. Some rain guards are made of resin, while others are made of plastic. In terms of thickness and flexibility, resin materials generally offer better quality. Poor-quality adhesive can affect the performance of the rain guards, and if not properly attached, the rain guards may be washed away during heavy rain.
