What are the pros and cons of rain guards?
3 Answers
Prevents rainwater from entering the vehicle, avoids rain being blown inside, ensures airflow does not affect driving or passengers, provides shade, reduces glare that could impair driving visibility, improves interior temperature, and helps eliminate odors. However, the shape of rain guards may not perfectly match the contour of the window edges, potentially leading to minor warping or gaps in certain areas. These imperfections can become sources of wind noise and inadequate adhesive strength. Installation method for rain guards: Peel off the 3M adhesive on the rain guard and gently attach it along the upper edge of the window. Once the positioning is confirmed to be accurate, press firmly along the edges to ensure the rain guard adheres securely to the vehicle. Material of rain guards: A protruding rain visor made of synthetic resin or engineering plastic.
I've been driving for over a decade, and rain guards are indeed convenient. On rainy days, you can crack the window slightly for ventilation without getting the interior wet or worrying about fog obstructing your view. It's especially helpful for families with elderly or children who get carsick—opening the window for fresh air makes them much more comfortable. However, there are downsides: at high speeds, the wind noise becomes very noticeable, creating a loud rattling sound. They also affect the car's sleek appearance, and if not installed securely, the adhesive strips can age and turn yellow. Plus, while you can open the window in the rain, heavy downpours may still splash water inside. So, it really depends on personal needs. Those who smoke or frequently take long trips might find them worthwhile, but if you prioritize aesthetics and quietness, they're probably not the best choice.
As a parent who frequently needs to pick up and drop off children, I find the rain visor quite practical. It allows air circulation during rainy days, preventing children in the back seat from feeling stuffy. Moreover, it's affordable and can be installed by oneself. However, the downsides are obvious: increased wind resistance after installation leads to higher fuel consumption at high speeds. Additionally, visibility is reduced, especially with an enlarged blind spot near the A-pillar, requiring extra caution when turning. It's indeed useful in rainy southern regions, but its utility diminishes in the dry northern areas.
