is PPF a points loser?

It should be a deduction whether you drive it or not. Owners know they are altering the appearance with a big sticker.

 

The following statements are based on the guidelines issued by the IAC/PFA which are followed at events such as Pebble Beach, Cavallino and FCA Nationals:

* If the film does not detract from the original appearance of the automobile, no deduction should be taken.

* If the film has been applied poorly, expect a deduction.

* If the film is excessively aged, damaged or discolored, expect a deduction.

* If the film (or colored vinyl) alters the original appearance of the automobile, expect a deduction.

To address the original question; "is PPF a points loser?" Yes - it can be, depending entirely on its execution and condition.

Drive your damn car.
