Cover your car under raining might sound like common sense but many car owners still underestimate how harmful rain can be. Sure, it looks gentle, even refreshing, but rainwater often carries hidden risks that could cost you thousands in repairs. 

In this guide, we’ll show you why rain is more dangerous than it looks and how a solid rainproof solution like the ones from US CAR COVER can be your car’s best defense.

Why is rain a hidden threat to your car?

When it comes to the effects of weather, many drivers assume that rain is not as serious as sunny weather. However, in reality, rain can cause serious damage if not handled properly.

• Damage from acid rain: Rain in urban areas often contains sulfuric acid and nitric acid. According to the U.S. Environmental Protection Agency (EPA), rain contains acid significantly accelerates paint corrosion, especially on cars that are parked outdoors for long periods of time.
• Frame corrosion and rust: Moisture continuously seeps into wheel wells, undercarriage gaps and door frames. In fact, rust-related repairs cost U.S. drivers more than $3 billion each year, and the majority of them are due to their cars being exposed to rain.
• Mold growth inside: Water intrusion and humidity are the perfect environment for mold. Cars that are stored outdoors in humid climates are 60% more likely to develop mold growth inside. This not only affects comfort, but also air quality and driver health!
• Electronics and sensor problems: Modern cars rely heavily on sensors and cameras. Without a rain cover, water can get into your backup camera, keyless entry system, and other components, leading to costly malfunctions and repairs.

So if you think skipping a car cover on rainy days is no big deal, think again. Using a high-quality car cover, like the ones offered by US CAR COVER, can create an effective rain barrier that protects both the exterior and interior of your car. A small investment can save you hundreds (or even thousands) of dollars in damage. Don’t wait until your car is rusted or your interior is faded to realize it was worth it!

How to effectively cover your car under raining?

Choose the right car cover

Not all car covers are rainproof. If you want to properly protect your car from the rain, you can’t just throw on an old sheet and call it a day. You need the right armor.

Here’s what to look for:

Waterproof

Many cheap covers are water-resistant, meaning they can handle a light drizzle. But for a real downpour or a tropical storm? 

You’ll need a completely waterproof cover with a polyurethane or PVC coating that won’t let a drop of water through. US CAR COVER’s premium line of covers are a solid choice here, having been tested to hold up to 1000mm of water pressure.

Breathability

It may sound weird, but you don’t want your car to be sweating underneath. A good rain cover should be multi-layered, with a breathable inner lining (like soft cotton or flannel) so moisture doesn’t get trapped inside and ruin the paint or cause mold.

Customized fit

Sure, regular covers can fit everything, but rain has a way of sneaking in around corners. Choose a well-fitting cover that’s made specifically for your vehicle type. They hug every curve and don’t flap like a kite in the wind. US CAR COVER has size charts for sedans, SUVs, trucks,  cargo vans, and even motorcycles .

Straps and buckles

Without sturdy straps, your cover is just a pretty umbrella. Look for models that have wind-stripping straps, underbody clips, or even wheel hooks. Bonus points if they have reflective strips so you can spot your car in low-visibility conditions.

Proper application techniques

So you've got yourself a car cover (preferably one from US CAR COVER). Now what? 

Here are a few techniques to cover your car in the rain like a pro:

Step 1: Always start clean

Rain brings enough dirt and grime. Don't let that filth get under your cover. Wash your car or at least wipe off any dirt before applying the cover. No one wants dirt and small scratches over time, right?

Step 2: Check the weather forecast, then the cover

If heavy rain is coming, choose a cover with a multi-layer waterproof layer and a breathable lining. This combination keeps water out but lets moisture escape, preventing unpleasant musty odors.

Step 3: Secure it as you like

Use the integrated strapping system, windproof buckles, and elastic to hold everything in place. Wind loves to sneak under loose covers and turn them into umbrellas. Don’t let that happen!

Step 4: Let the car breathe after the storm

After the rain stops, leave the hood open for a while. Let the car air dry and air out the interior if needed. Even the best covers retain some moisture, so this quick routine will keep things fresh and mold-free.

Additional tips to protect your car during the rainy season

In addition to using a car cover, consider the following additional measures:

• Regular maintenance checks: Inspect your vehicle regularly for signs of water damage or rust, especially after prolonged exposure to rain.
• Garage parking: Whenever possible, park in a garage or covered area to minimize direct exposure to rain.
• Apply sealant: Applying quality sealant to your car's paint can add an extra layer of protection against moisture and pollutants.
• Dehumidifier inside the car: Using a moisture absorbent inside the car can help keep humidity levels low, reducing the risk of mold growth.

So next time the sky turns grey and the first drops start falling, don’t just shrug it off. Cover your car under raining conditions with a quality, rainproof car cover to keep your vehicle safe from rust, mold, and expensive repairs. Think of it as a smart habit!
