Parking the car in covered spaces seems to be an increasingly complicated task these days. A large number of vehicles in Brazil makes it difficult for all places to have protected spaces, whether at work, at home, at college, or even on the street. 

Paying attention to this point is very important to keep, especially, the car's paintwork in excellent condition. For this, it is essential that all drivers understand how to protect the car from the sun, rain, and even hail.

In this text, we will show you how to mitigate the most aggravating factors of leaving your car exposed to weather events. Is there a way to protect the car from the sun? And protect the vehicle from acid rain, hail, and the like? What to do if the garage is uncovered and the car is left unprotected all day? Check out!

How do protect the car from the sun?

For you who have no other alternative and need to leave the vehicle exposed, there are some ways to protect your car from the sun. First, installing film on the windows, within the limits provided for by law, helps to control the internal temperature of the car and protects both the seats and plastics. 

Still without insurance for your car?

With the innovation and variety of insulfilm products, there are models that allow filtering of up to 99.9% of UV rays, directly impacting the internal temperature. These same models can block up to 97% of the infrared rays, thus intercepting about 60% of the heat that enters through the windows.

In addition, there are other ways to ensure greater durability for car paint due to rain and sun damage. See below for some suggestions.

How to protect car paint from the sun? 

Never wash your car and let it dry in the sun. 

This is a mistake that many people make. If you usually wash your car at home, never let it dry in the sun. After washing the vehicle, use flannels that absorb water very well and choose to leave it in the shade so that possible wash residues dry naturally. After washing, to give the finish, it is recommended to use waxes that filter the sun's rays. With this, you will have a more protected car.

Protective covers and sunshades help

Whenever possible, use a cover on your vehicle, but be careful when choosing, as some, because they are of low quality, can scratch the paint. Opt for soft fabric covers that do this solar filtering role. If you can't use covers, opt for sun covers, which will minimize the internal temperature and protect the car's dashboard and seats.

In case your seats are made of leather, there are products indicated for the hydration of the fabric, reducing the possibility of cracks or dryness. Use periodically to ensure the longest duration.

Paint glazing

This is a process indicated to be carried out after polishing. Vitrification is a technique that consists of a protective resin that totally isolates the car's paint, minimizing damage to the paint, such as the actions of time, such as acid rain, excess sunlight, not to mention scratches, animal waste or small scratches.

This is one of the most suitable techniques for those who have to leave the vehicle outdoors and want to protect the car from the sun or rain. The vitrification lasts an average of 3 years and eliminates, for example, that you have to crystallize or wax the car during this time.

How to protect the car from hailstorms?

In addition to understanding how to protect your car from the sun, there are other weather actions that can cause even more damage than the sun's rays, such as hail. But, in these cases, how to protect the vehicle?

Well, this is a tricky situation, even more so if you are on the street or on a road. If you noticed that the hailstorm has started, look for a covered place as soon as possible, such as a gas station, shopping mall parking lot, or even under an overpass. If that's not possible, try to park somewhere that is upwind to minimize the effects of ice boulders.

If you are at home and your garage is uncovered, choose to use the car's own floor mats to protect the parts that are most exposed, such as the roof, hood, and windshield. If you have tarps, blankets, and comforters, use them to further minimize the impact of hailstones. The more you can protect, the better.

What does climate change have to do with this damage?

When we talk about how to protect the car, it is worth remembering that not only vehicle care matters, but general awareness.

Much of the damage that can happen to them has to do with climate change. Did you know? 

The incidence of some natural phenomena, such as stronger rains or windstorms, may be related to environmental impacts, which, many times, have the action of man as an intensifier.

See a little more about that below:

Humanity's impact on the climate

According to the UN (United Nations), the impact of humanity on the climate is a fact. The increase in pollution, the intensification of industrial activities, and the exploitation of geographic space and resources are causing profound changes in the balance of the planet.

How does this impact car damage?

 Examples of climate change due to this and the intensification of phenomena that cause more damage to cars are the hailstorms themselves and the increase in temperature, with sunlight having the potential to cause greater damage, including the destruction of the ozone layer.

With the earth's surface getting warmer, the heat (which can cause internal parts and materials to be damaged, such as seats and rubber) also rises. When the car is exposed to the sun or is stored without a cover, the problem is even greater.

Another factor is the possibility of flooding, mainly due to pollution and clogged drains or excess garbage on the streets. In this sense, it is necessary to be very careful even with the wiper blades. Therefore, it is always necessary to understand how to protect the car.

What to do to protect yourself?

In addition to taking care of the vehicle in general and the place where the vehicle is left, having insurance against damages from nature is very important.

Doing our part too and trying to keep the places we inhabit in good condition is equally important. This is a collective responsibility and everyone tends to gain from a joint effort.

In relation to occurrences of flooding, it is valid to know the history of the place. If it is a very risky day, with heavy rains, and a complicated area, it is best to avoid it. Only if the appointment cannot be left for later is it recommended to go but to take all possible precautions.

This includes stopping in a safer place, looking for covered parking if possible, and not overexposing the vehicle. Minimizing risks and knowing how to protect the car is another factor taken into account by insurers when a claim is analyzed.

What are the main damages caused by leaving the car in the sun?

mechanical part

Creating some protection habits is essential to ensure your car is in optimal condition, as it is not only the paintwork that suffers from excessive exposure to UV rays – the mechanical part, such as the engine, is also highly harmed by this. For those who believe that a cover is enough, we suggest reviewing some concepts, because, in addition to everything, they can bring other damage if they are not chosen correctly.

internal plastics

For starters, leaving the car in the sun directly impacts the vehicle's internal plastics, such as the dashboard and doors. When exposed to a temperature of approximately 35°C, the constant weather can cause plastics to reach up to 65°C. With this, they will dry out quickly and may even become white, affecting the aesthetics of the car and losing value in a possible resale.


Another significant factor when we talk about exposing the car to the sun is the paintwork. Experts point out that cars with dark colors, such as black, red, blue, and green, are the ones that suffer the most from the action of time. This has a scientific reason: they absorb more energy and the paintings are compromised. 

The main wear that will be noticed over time is the lack of shine in the paint. In more extreme cases, the paint can create small cracks and become brittle. This will generate an extra cost to be repaired, for example, so that there is no further devaluation.


Another part of the vehicle that is harmed is the seats. Those who have fabric car seats will notice over time that they will fade, especially if they are dark. For leather seats, the damage can be even greater, as leather tends to dry out and need to be replaced over time.

finishing items

In addition to the parts that were mentioned, car finishing items, such as bumpers, fenders, and plastic mirrors, not to mention the sealing rubbers, will also be damaged over time and overexposure to the sun.

Auto insurance offers coverage against hail

But, to ensure much more tranquility in the event of a hailstorm, the best option is to hire Auto Insurance. When purchasing this product, you can include a hail cover. 

That's why it's very important to talk to your broker to find out if, in the negotiation, you included coverage against natural disasters in your policy – ​​it covers damage caused by hail. In addition to hail, this coverage protects the insured in cases of lightning that may strike the car and cause fires, a tree falls due to storms, earthquakes, and windstorms, among others.

During the conversation with your broker, he will ask where your vehicle is parked and this will certainly impact the final price. A vehicle that sits on the street, for example, tends to have more expensive insurance than a vehicle that is in a covered garage.
