What Should You Do If It Rains After Applying PPF on a Car

After applying Paint Protection film (PPF) on a car, it is generally not recommended to expose the car to rain immediately. This is because the freshly applied film has not yet fully adhered to the car's surface and requires time to settle properly. Additionally, there may be tiny air bubbles trapped under the film, which need to be exposed to sunlight to evaporate.

If it rains during this period, the low temperature and cold air could cause the air bubbles to contract rather than dissipate, negatively affecting the adhesion of the film. Moreover, the edges of the freshly applied film are not very secure, particularly around the corners of the car, where there is a risk of the film peeling.

However, if the rain is light and no major issues arise, it usually won't be a problem. If you notice any peeling or an increase in air bubbles, you should promptly contact the service center to have it addressed. If left unattended, these issues could worsen over time.

What Causes the Paint Protection Film to Peel After Application? How Should It Be Handled?There are two types of peeling: one that can be remedied and one that cannot.

Peeling that can be remedied

Peeling caused by external factors can generally be fixed. It is important to return to the service center as soon as possible to have the film reattached properly. There are three common scenarios where peeling can be remedied:

1.The "wet application method" is commonly used for applying PPF, which can leave some moisture under the film. This reduces the adhesion of the adhesive layer, leading to peeling.

2.If the car is washed just a few days after the film is applied, the edges of the film may be affected by the high-pressure water jets, causing the film to peel.

3.Driving at high speeds on highways soon after applying the film can cause the wind to lift the edges, leading to peeling.

Peeling that cannot be remedied

Peeling that cannot be remedied is usually due to product quality issues. In such cases, the film cannot be repaired, and the only solution is to have it replaced under warranty. Low-quality products often lack adequate after-sales service. In these instances, the only option is to remove the inferior film and apply a high-quality product. Poor-quality films not only fail to protect the car's paint but can also damage the original paint. Removing the film as soon as possible is necessary to prevent further damage.

The best way to prevent these issues is to choose a high-quality PPF from a trusted  brand and have it applied by a professional installer. High-quality films come with a warranty, and if any issues arise later, they can be addressed through after-sales service, saving you a lot of trouble and providing peace of mind.

Two scenarios where peeling cannot be remedied

1. The installer used poor-quality adhesive, causing the film to peel when the adhesive fails.

2. Some films are low-quality products that shrink over time, leading to peeling.

Details to pay attention to after applying  PPF

1. Do not wash the car within four days of applying the film. After four days, it's generally fine, but if you're unsure, you can return to the service center to have the film checked.

2. If you notice foggy moisture or water droplets under the film, don't worry. These should naturally disappear after about a week of exposure to sunlight.

3. Avoid driving the car immediately after applying the film; it's best to let the car sit for a few days.

4. Avoid high-speed driving to prevent the paint from being subjected to strong impact.

5. Do not rush to wash the car. If you need to wash the car later, inform the car wash staff that the car has paint protection film, and advise them not to spray high-pressure water directly at the film's edges.

6. Avoid parking the car under trees to prevent bird droppings or tree branches from damaging the film. If the car is exposed to bird droppings or tree sap, clean it promptly with a wet cloth, as these substances are highly corrosive and can damage the film if not cleaned quickly.

7. Do not use tar remover, degreasers, or other harsh chemicals to clean the car's surface. Only use specialized cleaning agents designed for paint protection films.

8. After some time, once the film has fully adhered to the car's paint, you can wash the car as usual. Regular washing, about once every two weeks, helps maintain the film.

9. If you notice the film edges lifting, do not attempt to fix it yourself. Contact the service center immediately and bring the car in for a warranty inspection.
