PPF vs ceramic coating, answered straight

What is the difference between PPF and ceramic coating?

Short version: film is armor, a coating is a force field for everything except impacts, and the strongest builds in our shop wear both.

Why can PPF stop a rock chip when a ceramic coating cannot?

Because one of them is a sheet and the other is a skin, and the gap between them is not a matter of degree. Paint protection film is 8 mil of thermoplastic urethane, a physical layer thick enough to deform, absorb the energy of an impact and spread it out before it reaches your clear coat. A ceramic coating is a liquid resin that cures onto the clear coat and ends up a few microns thick, which is millionths of a meter. There is nothing there to absorb anything.

Hardness ratings confuse this, understandably. Gtechniq Crystal Serum Ultra is rated 10H and Crystal Serum Light 9H, and those are real numbers describing real scratch resistance. But hardness is resistance to being marred, not resistance to being hit. A pane of glass is harder than a phone case and you know which one you would rather drop your phone in. The coating wins against a gritty wash mitt, a fingernail at the door handle and the swirls a tunnel wash puts in. It has never had a mechanism for stopping a stone off the back of a gravel truck at 60 miles an hour, and no coating brand that is being straight with you claims otherwise.

The film's other trick runs the same way. STEK builds DYNOshield with a self-healing top coat, so light swirls and wash marks sit in an elastic layer that relaxes back into shape with heat from the sun or warm water. A coating is hard rather than elastic, so what it resists it resists permanently, and what gets through it stays. Two different strategies against two different problems.

How much does PPF cost compared to ceramic coating?

Film is the more expensive product, and it is not close. Below is what we publish for each. Ceramic coating rows say "quoted per vehicle" because that is genuinely how coatings are priced here: size and paint condition decide the work, and a corrected two-seater and a swirled SUV are different jobs even when the same bottle ends up on top.

The useful way to read that table is per square foot of car rather than per line item. A coating covers every painted panel plus wheels and glass for a fraction of what filming a full vehicle costs, which is why the coating looks like the value buy right up until a stone hits your hood. Film buys you protection against exactly one category of damage that the coating cannot touch, at a price that reflects it. Detail on either side lives in the PPF cost guide and the ceramic coating cost guide.

Which one lasts longer, PPF or ceramic coating?

On the published paperwork, film. STEK warranties DYNOshield and DYNOmatte for 10 years against delamination, yellowing, bubbling and cracking. Gtechniq Crystal Serum Light carries a five-year manufacturer guarantee at 9H, and Crystal Serum Ultra is a dual layer at 10H guaranteed for up to nine years, released only to accredited detailers. EXO v5 is a hydrophobic top coat that layers over either one rather than replacing it.

Those numbers describe the durability of the products, not a prediction about your car, and the honest caveat cuts both ways. A coating that gets washed with a dish sponge in a driveway will not read like a nine-year product no matter what the bottle says, and film on a car that lives outside under a maple asks more of the top coat than film on a garage queen. What is genuinely different is the failure mode at the end. A coating that has stopped beading is renewed by decontaminating and reapplying. Film that has taken a decade of hits comes off, and the factory paint underneath comes out looking like the day it was covered, which is the part owners tend to underestimate until they sell the car.

Should you get both, and in what order?

For most cars that see real highway miles, both is the right answer, and the order matters more than people expect.

Paint correction first, if the paint needs it. Both products are permanent-ish layers going over your clear coat, and both lock in whatever is underneath. Swirls that go under a nine-year coating stay there for nine years. Marks that go under 8 mil of film are sealed in until the film comes off. Correcting after the fact means undoing work you already paid for.

Film on the impact zones. That is the front bumper, hood, fenders and mirrors at minimum, because that is where road debris lands. Add the windshield in DYNOtop if your commute sits behind gravel trucks. A full front end at around $2,000 covers the overwhelming majority of what actually chips.

Coating over everything else. Here is the part specific to STEK: DYNOshield already has a hydrophobic top coat built in, so unlike most films it does not need a coating over it to bead water. What the coating is really for in a combined build is the painted panels the film does not cover, plus the wheels and glass, so the whole car sheds water and releases dirt the same way instead of behaving like two different cars at the hose.

Done as one drop-off, that is one decontamination, one correction and one process rather than three visits and three prep bills. We quote it as a package for exactly that reason.

Which film and which coating does SeaWraps install?

On the film side, STEK. We are a STEK Certified Installer and we lay DYNOshield in gloss and DYNOmatte in satin, both 8 mils with self-healing top coats and 10-year manufacturer warranties, plus DYNOtop for glass. If you are weighing that choice against the other name people bring up, our STEK vs XPEL comparison puts both manufacturers' published specs side by side and explains why we landed where we did, including the rows where XPEL publishes more than STEK does.

On the coating side, Gtechniq. Crystal Serum Light is the foundation at 9H with a five-year guarantee, Crystal Serum Ultra is the flagship at 10H with up to nine years, and EXO v5 is the hydrophobic top coat that goes over either. Ultra is restricted to accredited Gtechniq detailers, which is why it is not something you will find on a shelf. The full ladder, including wheel, glass and interior coatings, is on the ceramic coating page.

Whichever way you go, the thing that decides how your car looks in five years is not the logo on the bottle or the roll. It is whether the paint was properly prepped, whether film edges were wrapped rather than cut on the panel, and whether the coating went down in a clean bay on genuinely decontaminated paint. Ask any shop about that before you ask them about brands.
