How long after applying a paint protection film can the car be exposed to rain?

[LeValeria]

The car should not be exposed to rain for at least three days after applying a paint protection film. Here is more relevant information: 1. In addition to common dust and airborne particles, urban rainwater also dissolves various substances such as sulfates, chlorides, carbonates, and organic compounds. 2. The damage caused by rain is not only due to the corrosion from acidic substances but also from the burning effect on the car paint when sunlight refracts through raindrops after heavy rain. 3. Therefore, experienced car owners will use a clean cloth to wipe off water droplets from the car paint surface after heavy rain. Many car owners choose methods like waxing, crystal coating, or painting to protect the car paint, but these methods are all based on altering the original paint surface.
