Foam It On. Rinse It Off.
Drive Away Protected.
Wet Application Sealant. UV Protection. The efficient sealant for the vehicle that lives its life rather than sitting for detailing.
Koch Chemie Hydro Foam Sealant S0.03 is a concentrated wet-application sealant with a dilution range of 1:50 to 1:150. Apply after the vehicle has been fully washed and rinsed — blanket the still-wet surface with foam, allow a brief dwell, and rinse off completely. That's the process.
S0.03 provides UV protection and rejects water and wet contaminants from the surface. Safe on glass, paint, and trim. It delivers a temporary protective layer in the same way a towel-applied sealant would — the durability expectation matches that format.
It also contains glossing agents that effectively mask fine scratches and surface imperfections throughout the durability term — making it a strong option for the vehicle that sees daily use and has a budget-conscious owner or customer in mind. At roughly 20ml per application in a 1L foam cannon at 1:50, the cost per use is very low.

"Perfect for the vehicle that sees more use than time parked for detailing — with a budget-conscious user or customer in mind."
— Koch Chemie · Hydro Foam Sealant S0.03What S0.03 does
Sealant in the Rinse Step Protection applied during the wash process rather than as a separate step. Foam it on a wet surface, let it dwell briefly, rinse off — the sealant bonds during that window without adding time to the wash routine.
Glossing Agents — Masks Fine Scratches The formula includes glossing agents that fill and visually mask fine surface scratches and imperfections throughout the durability term. Not a correction — but an effective way to keep a daily driver looking better between proper details.
UV Protection & Water Rejection Repels water and wet contamination from paint, glass, and trim surfaces while providing a UV-protective layer — the core function of any sealant, delivered efficiently through the foam application method.
Exceptionally Low Cost Per Use At approximately 20ml per wash in a 1L foam cannon at 1:50 dilution, a single bottle covers a significant number of applications. For budget-conscious customers or high-frequency wash programs, the math is compelling.
Dilution & Application
Apply to an exterior surface that has already been fully washed and rinsed. Foam over the wet surface for even dispersion and coverage. Allow to dwell briefly — do not let it sit long enough to dry. Rinse off completely.
Do not pre-mix and store. Measure out fresh with each use. Manage your environment during application — avoid prolonged dwell time, particularly on glass, as this causes streaking and spotting.

The segment is competitive and time will be the judge. What we know now: the process is sound, the cost per use is low, and the glossing agents deliver a visible result every wash. Notes on real-world durability comparison will be added here as they become available.

Do not pre-mix and store S0.03. Measure out the appropriate amount with each use. Pre-mixed solution does not maintain shelf stability and should not be prepared in advance.
Real-world durability data is pending. S0.03 is a new addition to the lineup and has not yet accumulated enough field time for a reliable comparative durability figure. Notes on real-world effectiveness and segment comparison will be added to this description as they become available. The competition in this segment is strong — time and application process will be the judges.
