PPF, ceramic coating, or a wrap?
These three get mixed up constantly, so here is the short version. A ceramic coating is a chemical layer. It changes how water and dirt behave on a panel and it makes washing easier. It will not stop a stone. PPF is a physical layer thick enough to absorb an impact. A printed wrap is also a physical layer and it does shield the paint, but you trade away the factory color and gain a surface you can print a brand on.
On commercial work the answer is often not PPF at all. A wrapped van already carries cast vinyl over the sheet metal, and we laminate print with 3M 8518 gloss overlaminate for road salt and UV, so the paint underneath is covered. Where film earns its keep on a fleet is the unwrapped front cap of a box truck, the mirror arms, and the hood of a pickup nobody wants to repaint. On a leased vehicle the logic shifts again: film on the hood, bumper and rockers, pulled before turn-in, hands the paint back the way the lease expects to find it.
What is warranted, and by whom?
Three different terms get blurred together in this category, so here they are apart. A paint protection film carries a manufacturer film warranty against yellowing, cracking and delamination, and that warranty is the film maker's to honor, not the installer's. Chicago Fleet Wraps installs no film, so none of it is ours either way.
On wrap work the terms are ours to state. Chicago Fleet Wraps backs its own installation with a 2-year workmanship warranty covering qualifying installation-related lifting, peeling, bubbling and edge failure under normal use, subject to the written warranty terms, and the printed vinyl is separately covered by a 5-year material warranty for qualifying material defects. Expected service life of 5 to 7 years is neither of those. If a shop quotes you one number that supposedly covers film, labor and service life all at once, ask which company is actually standing behind each part of it.
