Yes bro, but super ultra deep cuts from a key or stone will obviously penetrate through the film and damage the paint, but ppf still helps to reduce the damage significantly when compared to a vehicle without ppf.
Also, bro I can't agree with this.
Sir, ye to wohi baat ho gai aap apnay oont ko khula chor den. Aur phir kahe mujhe tawakkul hai. Aur aap Ayatul Kursi parh kar phok de, aur kahen yah kahin nahi jaega ab.
Pahle aap oont ko bhante hain ~ take the necessary steps to protect it and then the tawakkul comes, similarly first you take necessary steps to protect your car and then tawakkul comes sir.
Point is ~ Take the necessary steps to protect your car, and then tawakkul.
