"Car PPF, or Paint Protection Film, is a transparent and thin layer of film applied to the exterior of a vehicle to protect its paint from stone chips, bug splatter, bird droppings, road tar, and other potential damages. PPF is often made of polyurethane or a similar material that is resistant to abrasions and impacts.
The primary purpose of PPF is to provide an additional layer of defense for a vehicle's paint, helping maintain its appearance and resale value over time. It can be self-healing to a certain extent, meaning minor scratches and swirl marks can disappear with exposure to heat."
