PPF is useless, until your first stone chip then you curse and swear while standing there staring at it every day wondering why you just didn’t spend the money to protect the thing that brings you joy.
I think of PPF the same way I think of car insurance, I hate paying for it but when you need it, it’s there. I got the entire front part of the car covered in PPF including lights windshield and mirrors Then I ceramic coated the entire thing including rims and calipers, now nothing sticks not even brake dust, spray it down with the hose and it all washes off no real physical labor involved. In total it cost me $3000. No regrets well worth the money.
