Four questions to answer questions about the paint protection film rain spots

When it rains, the surface of the car paint protection film forms a circle-like stain, either solid or hollow, which is called rain spots. The root cause of the formation of rain spots is that the rainwater droplets are not removed in time after falling onto the surface of the car paint protection film, and the minerals in the rainwater attach to the surface of the car paint protection film.

According to the different natures of rain spots, they are divided into two types: removable and irreversible, no matter which one they are, they have caused a certain amount of trouble to car owners. We have sorted out the four questions that car owners and friends are most concerned about, and we will answer them in detail through this article, hoping to help you.

The rain spots can be wiped off with a light wipe, indicating that there is more dust in the rain, floating on the surface of the car clothing, and it is naturally easy to remove; However, rainwater often contains soluble minerals such as calcium, magnesium, sodium, etc., which we cannot see with the naked eye.

Theoretically, the higher the density of the coat coating, the better the stain resistance and the less likely it is to produce rain spots. However, considering the differences in climate in various regions, and the different car environments and usage habits of different car owners, the factors that lead to rain spots in the car clothing are more complex, therefore, the statement that "the appearance of rain spots in the car clothing means that the quality of the car clothing is not good" is one-sided and not objective.

If the surface of the car clothing is formed in a hollow circle, and the stain in the middle of the circle is light, it means that the stain has not penetrated into the TPU substrate, and the overall anti-fouling performance of the car clothing is excellent, and the car wash can be effectively removed under normal circumstances.

If it is a solid circle of rain spots and the center color is dark, it is necessary to pay attention to the fact that the coating of the clothing itself has poor corrosion resistance and compactness, and the rainwater can easily penetrate into the substrate to produce chemical reactions; Either the car has not been washed for too long, and the substance that was originally only attached to the surface of the film has penetrated deeply into the TPU substrate, forming irreversible rain spots. Regardless of the cause of stubborn rain spots, you should go to the store as soon as possible to see if you can wash off with a weakly acidic car wash liquid, and remember not to use a strong acid and alkaline car wash liquid, because this will cause more serious damage to the car coat coating. If the weakly acidic car wash liquid cannot remove the rain spots on the car coat, it is recommended that you tear the film directly, so as to avoid serious chemical reactions between the rain and the car coat, resulting in a larger corrosion area, and even affecting the original car paint.

After the rain, you must wash the car in time to avoid all kinds of substances in the rainwater from penetrating into the car clothing, causing irreversible rain spots. If you want the car clothing to maintain a long-term bright effect, you should return to the store regularly for re-inspection and maintenance. Note: Vehicles without clothing need to be washed in time after rain, because the paint surface without clothing protection is more susceptible to rain erosion.

---------------------

Rain spots or water stains in the car coat have a certain degree of chance, and the compactness of the car coat coating, the time of the car coat, the local rainfall frequency and the car owner's car habits are all related, scientifically speaking, there is no car coat can completely eliminate the rain spots, water stains, but the use of high anti-fouling hydrophilic coating of the car coat rain spots or water stains probability will be low, according to the past industry experience can generally be less than one percent.

Therefore, if there is a very small amount of rain spots or water stains on a certain brand of car clothing, there is no need to panic, try to remove them first with conventional methods, and if the rain spots are irreversible, they need to be replaced for customers in time.

However, if there are large-scale and batch rain spots and water stains on the brand's clothing, it is generally still attributed to the product itself.
