How Long Does PPF Last? 5 to 7 Years, Then the Cycle Starts

The sun comes first, because film yellows and dulls the finish under sustained UV. Cheap off-brand film can start yellowing as early as year 3, and even good film by year 5, years before it has to come off, most visibly on hoods and roofs where the UV load is highest. Once it yellows, there's no fix, only replacement. Install quality matters just as much, film that wasn't cut precisely or prepped properly fails early and usually lifts at the edges first, and it can look perfect for six months before it starts peeling. Every install also has cut lines at the panel edges, and those recessed seams collect dirt and moisture and become the first place the film lets go as it ages. Where the car lives is the accelerant, a car parked outside in year-round sun ages film faster than a garaged one, and almost nobody factors that in when they're quoted a lifespan. You mostly don't notice any of it while it's happening, because the film ages evenly across the whole car, and it took a client coming back for one replacement panel on a black car for us to see how far the rest of it had gone.
