Been lurking here for a while and PPF comes up constantly but I’ve never actually understood what it is. I assumed it was some kind of polish or wax until someone corrected me. Now I feel a bit silly asking but I’d rather know than keep nodding along. I found a Helpful guide explaining what PPF is and it finally made sense, it’s basically a clear film stuck onto the paint rather than a liquid product. So my next question is, does it actually look invisible on the car or can you tell it’s there up close? And does it change how you wash the car afterwards? I’m considering it for a new car but I want to understand the practical side before committing.
