Ceramic Coating - this will last up to 5 years but also depends on how the car is stored (garage/outside) and environmental factors like rain, proximity to the sea and sunlight.

Ceramic Spray - this a effectively a quick detailer. Wash the car and then spray on and wipe off. This type of product will help maintain a coated car as it bonds to the existing coating and ‘layers’ over the top - effectively extending the life of the existing coating. The spray coating will provide 3-6 months of additional protection again depending on the environmental factors outlined above.

Ceramic Glass Coating - this is great for windscreens and has a similar result as say Rain-X. The screen needs to be really clean before applying so using a water-spot remover or Isopropyl Alcohol first is critical. The challenge with ceramic coatings on windscreens is the wiper blades so they effectively scrape the coating off. We love the Hermosa Glass Coating because once applied to the screen (spray on, let set, polish off) you can add the solution to the windscreen reservoir so that every time you clean the screen, you effectively re-apply the coating.

Ceramic Shampoo - this is our best-selling product. You can add to a foam cannon or bucket wash method. It has high levels of SiO2 so also bonds to the paintwork or existing coating to restore the shine. Id recommend drying with a Rapid Dry Towel or similar after you hose off and it really does deliver on its promise of high shine - but it does only last 4-6 weeks. You will notice the hydrophobic properties revert back to pre-wash after that time.

It depends on two key factors: the specific product you're using and how well the car is maintained.

Hermosa 10H Graphene Ceramic Coating offers up to 5 years of protection, maintaining its hydrophobic effect (repelling water) throughout that time.
Hermosa Ceramic Spray provides protection for around 3 to 6 months.
Hermosa Ceramic Shampoo typically lasts 4 to 6 weeks per application.

Maintenance plays a major role. For example, if a Hermosa Ceramic Coated car is parked by the seaside and regularly exposed to salt spray, the coating will degrade faster than a car that’s kept undercover and washed monthly with Hermosa Ceramic Shampoo.

Our Ceramic Shampoo contains silicon dioxide (SiO₂), which bonds to existing ceramic layers—helping to repair minor imperfections and extend the life of the coating.

Yes they can - as long as you follow the instructions and keep your car out of direct sunlight, wind and rain after application then your finish will be as good as the professionals!

We would recommend you remove the existing coating before applying the Hermosa Graphene Ceramic Coating just in case the formulations have any issue layering. Simply cut and polish your car and use IPA before applying the Hermosa Graphene Ceramic Coating. Full details can be found in the Hermosa Guide section.
