What Causes Spots on Corroded Paint Protection Film?
2 Answers
Paint protection film corrosion with spots occurs because it has reached its service life. Here is an introduction to the functions of paint protection film: 1. Protective function: Crystal clear, wear-resistant, scratch-resistant, yellowing-resistant, and reduces impact vibration. After installation, it provides protection against tar, tree sap, insect fluids, bird droppings, acid rain, and saltwater corrosion. 2. Repair function: Maintains metal, ABS plastic, paint surfaces, and organic materials, and can repair minor scratches on poor-quality materials. 3. High-temperature resistance: Withstands water impact at 5MPA, high temperatures up to 150 degrees, and low temperatures down to -80 degrees; excellent composite materials maintain performance on complex surfaces without altering product properties.
When washing my car the other day, I noticed several small spots on the paint protection film, as if something had corroded it. Thinking back, it might be because bird droppings weren't cleaned promptly when parked roadside, combined with recent frequent rain - the acid rain eroded and formed these spots. Another time, I used household cleaner to wipe the car, and those chemicals directly reacted with the film. If left untreated, this corrosion can spread and cause more severe damage. It's advisable to get it checked or have the film replaced at a professional shop as soon as possible. Don't attempt DIY fixes as you might tear the film - specialized cleaning products are best for preventing such issues. Avoid parking under trees or near pollution sources regularly. Developing good maintenance habits can significantly extend the film's lifespan, saving money and ensuring peace of mind.
