Where XPEL PPF is installed, we use appropriate XPEL products on the film so it remains within the correct XPEL system. On the rest of the vehicle, customers can choose either suitable XPEL protection or our Gtechniq ceramic range. That lets us build the package around the customer without compromising the PPF system.
Paint Protection Film and ceramic coating are often discussed as alternatives, but they solve fundamentally different problems. XPEL PPF is a physical sacrificial barrier designed to protect paint against stone impacts, road debris and light abrasion. Ceramic protection is much thinner and is primarily used for chemical resistance, hydrophobic behaviour, gloss and easier maintenance.
Used together correctly, the two systems complement each other extremely well. The important part is product compatibility and installation order. Surface Works is both XPEL Certified and Gtechniq Accredited, so we can specify the film and surface protection around the areas of the vehicle being treated rather than forcing one product family onto every surface.
What does XPEL PPF protect against?
XPEL Paint Protection Film sits physically over the original paint and acts as a replaceable sacrificial surface. It is particularly effective against normal stone impacts, road debris, light abrasion and the type of damage that accumulates on exposed body panels.
This is why PPF is the correct starting point when a customer is primarily worried about stone chips. A ceramic coating cannot reproduce that physical protection because it is far too thin.
For many road cars, full-front XPEL PPF gives excellent protection to the bumper, bonnet, front wings and mirrors. Extended or full-car coverage can then be chosen where mileage, body shape or the owner's priorities justify it.
What does ceramic protection add?
Ceramic protection works at the surface. It can improve slickness, water behaviour and resistance to environmental contamination while making the vehicle easier to wash and dry.
That is useful on both protected and unprotected areas, but the product used needs to suit the surface underneath it. Film and automotive clear coat are different materials and do not automatically need the same coating.
Surface Works therefore treats ceramic protection as part of the wider protection specification rather than simply applying one product over everything.
Why do we keep XPEL PPF within the XPEL product system?
Where we have installed XPEL PPF, Surface Works uses the appropriate XPEL products over that film. We do this to keep the PPF within the intended XPEL system and avoid introducing an unrelated coating over a warrantied film installation.
That is particularly important because the film already has its own engineered surface and applicable product warranty. The coating added over it should complement the XPEL system rather than create uncertainty around compatibility or aftercare.
This does not mean the entire vehicle has to use XPEL products. It means the PPF itself stays within XPEL.
Can Gtechniq ceramic coating be used on the rest of the car?
Yes. If a vehicle has partial PPF — for example a full-front XPEL installation — the remaining unfilmed paint can be protected with a suitable Gtechniq ceramic coating if that is what the customer prefers.
Surface Works is Gtechniq Accredited and offers GT1, Crystal Serum Light and accredited-only Crystal Serum Ultra. That gives customers a choice of coating duration and budget for the paint that is not covered by PPF.
The result can therefore be XPEL PPF with XPEL-compatible surface protection on the film, combined with Gtechniq ceramic protection on the remaining painted panels.
Can XPEL products be used on the rest of the vehicle too?
Yes. Customers who prefer to keep the whole protection package within XPEL can choose appropriate XPEL products for the remaining areas of the vehicle.
This can create a very straightforward single-brand protection and aftercare system, particularly for customers whose primary reason for visiting Surface Works is XPEL PPF.
The important point is that we can offer both approaches. We do not require a customer with partial XPEL PPF to use Gtechniq on every unfilmed panel, nor do we require them to use XPEL everywhere if a Gtechniq coating better matches what they want.
What does a mixed XPEL and Gtechniq package look like?
A typical example is a new performance car receiving full-front XPEL PPF to protect the highest-impact areas. The PPF receives the appropriate XPEL surface protection, while the doors, rear quarters, roof and other unfilmed paint receive a Gtechniq ceramic coating.
That gives the front end the physical impact protection of PPF while the rest of the vehicle benefits from long-term ceramic protection and easier maintenance.
The systems are separated according to the surface rather than mixed indiscriminately: XPEL products on XPEL film, and the selected Gtechniq coating on suitable unfilmed paint.
What does an all-XPEL protection package look like?
The same full-front PPF installation can instead be paired with suitable XPEL protection across the remaining vehicle if the customer wants a consistent XPEL package.
This can simplify product selection and ongoing maintenance because the vehicle's protection has been specified around one manufacturer.
Surface Works can explain the available options and help the customer decide whether an all-XPEL approach or XPEL PPF combined with Gtechniq on the remaining paint makes more sense.
Which Gtechniq coating can be used on the unfilmed paint?
GT1 is the shorter-term enthusiast-friendly option with up to 12 months of protection. It suits owners who like a more regular refresh cycle and can also be purchased from Surface Works for DIY application.
Crystal Serum Light provides up to five years of professional ceramic protection and is an excellent choice for customers wanting a substantial multi-year coating.
Crystal Serum Ultra is Gtechniq's accredited-detailer-only flagship coating, providing up to nine years of protection. Surface Works is Gtechniq Accredited and approved to install CSU. The choice normally comes down to ownership period and budget.
Does the PPF go on before the ceramic coating?
Yes. If PPF is being installed, the film areas need to be prepared for adhesion before any surface coating that could interfere with that process is applied.
The vehicle is washed and decontaminated, the paint is inspected and any agreed correction is carried out first. XPEL PPF is then installed onto the correctly prepared surface.
Only after the film installation is in place do we apply the appropriate surface-protection products to the PPF and remaining paint according to the agreed package.
Why shouldn't ceramic coating be installed under PPF?
PPF relies on controlled adhesion to the prepared vehicle surface. Applying a ceramic coating first can create a highly slick, low-surface-energy layer that is not the substrate the film installation is designed around.
If a vehicle already has ceramic protection and the customer later decides to add PPF, the coating in the installation areas may need to be removed appropriately before the film is fitted.
This is why it is worth planning the whole protection package at the beginning where possible.
What if the car already has Gtechniq ceramic coating?
That does not prevent the vehicle having XPEL PPF later, but the existing coating needs to be considered before installation.
Surface Works assesses the coating and paint first. Depending on the product and its condition, machine polishing or another appropriate preparation process may be required in the PPF areas to create the correct surface for adhesion.
Once the film is installed, the PPF areas are then kept within the XPEL product system. Existing suitable Gtechniq protection can remain on unfilmed areas where appropriate.
Does the paint need polishing before PPF and ceramic?
Not automatically. We inspect the paint after washing and decontamination. If the finish is already excellent, unnecessary machine polishing removes clear coat without adding meaningful value.
If swirl marks, haze or other defects would remain visible beneath the film or long-term ceramic coating, a single-stage or more involved correction can be discussed.
The objective is to create a finish worth protecting while preserving as much healthy original paint as possible.
Why is preparation especially important with a combined package?
A combined PPF and ceramic package can remain on the vehicle for many years, so anything left underneath it can remain visible for a long time too.
Bonded contamination, polishing residue and avoidable defects should therefore be dealt with before the protection systems are installed.
Surface Works deliberately operates a lower-volume workshop model, giving our XPEL-trained installers and detailing team more time for preparation, installation and final inspection.
Does ceramic coating make PPF more resistant to stone chips?
No. The physical impact protection comes from the PPF itself. A ceramic coating does not materially thicken the film or turn it into a stronger impact barrier.
The ceramic product over the film is primarily there to influence surface behaviour: slickness, hydrophobicity, contamination resistance and ease of cleaning.
This distinction matters because customers should know which product is doing which job.
Does PPF make ceramic coating unnecessary?
Not necessarily. PPF is excellent physical protection, but owners can still benefit from improved water behaviour and easier cleaning across the vehicle.
On a partially protected car, ceramic protection is particularly useful for the unfilmed paint because it gives those panels their own long-term chemical and maintenance protection.
On the PPF itself, the appropriate XPEL surface product can make maintenance easier without changing the role of the film.
Which package is best for a daily driver?
For a daily-driven car, full-front XPEL PPF combined with suitable protection over the film and remaining paint can provide an excellent balance.
The PPF handles the repeated frontal road impacts while the surface protection makes winter grime, insects and normal maintenance easier to manage.
The unfilmed paint can use XPEL or Gtechniq depending on the customer's preference, desired durability and budget.
Which package is best for a long-term keeper?
If preserving the entire vehicle is the priority, extended or full-car XPEL PPF can be considered. Full-car film gives the original paint a sacrificial layer across far more of the exterior.
For partial PPF on a long-term keeper, a longer-duration Gtechniq coating such as CSL or accredited CSU can make sense on the remaining paint.
Again, the film itself stays within XPEL. The longer-term Gtechniq choice applies to suitable areas outside the PPF installation.
What about wheels, glass and interior protection?
A combined exterior package can also include dedicated protection for other vehicle surfaces. Wheels, exterior glass, leather and fabrics each need products designed for those materials.
These areas are not protected simply because the body has PPF or ceramic coating. They are separate options that can be added where they solve a genuine maintenance or ownership problem.
Surface Works can specify these alongside the main XPEL and Gtechniq package rather than treating every add-on as compulsory.
How should a mixed XPEL and Gtechniq vehicle be maintained?
The vehicle should be washed safely as one car, but the protection systems on different surfaces still need appropriate aftercare.
For XPEL PPF, we recommend suitable XPEL-compatible maintenance products and avoid aggressive pressure directly into film edges. For Gtechniq-coated paint, we recommend appropriate Gtechniq-approved maintenance products.
Customers do not need to make washing unnecessarily complicated. We can explain a straightforward routine that respects both systems while keeping the vehicle easy to maintain.
What happens with warranties?
Keeping the products appropriate to the surfaces helps maintain a clear warranty position. XPEL PPF remains within the XPEL system, while Gtechniq coatings on unfilmed paint follow the applicable Gtechniq installation and maintenance requirements.
Crystal Serum Ultra is accredited-install-only, and Surface Works is Gtechniq Accredited. XPEL PPF is installed by our XPEL-trained team within our XPEL Certified business.
Correct maintenance still matters. Neither PPF nor ceramic protection should be treated as a fit-and-forget product.
The Surface Works recommendation
PPF and ceramic coating work extremely well together when each product is given the job it is designed to do.
Use XPEL PPF where physical impact protection matters. Keep the PPF itself within the appropriate XPEL product system. Then decide how you want to protect the remaining vehicle: suitable XPEL products for a consistent XPEL package, or Gtechniq ceramic protection where its range and durability better suit your requirements.
That flexibility is one of the advantages of Surface Works being both XPEL Certified and Gtechniq Accredited. We can build the protection around the customer and the vehicle rather than forcing every surface into one generic package.
Think of the vehicle in zones. XPEL PPF protects the panels that need a physical barrier, and those film areas stay within the XPEL system. The remaining paint can then use either XPEL or Gtechniq protection depending on the durability, budget and aftercare system you prefer.
