About KERUISEN
KERUISEN makes two polishing compounds: S8 for sheet metal and paint, S9 for universal car paint polishing. Factory-direct from a manufacturer with 15 years of OEM/ODM experience.
A manufacturer first
KERUISEN makes polishing compounds. For 15 years we have developed and produced formulas for OEM and ODM partners, and we now bring that same manufacturing experience directly to car enthusiasts, detailers and body-shop professionals. Our mission is simple: professional-grade results, an easy process and honest value from the factory.
Made in-house, from batch to bottle
Our production base covers 100,000 m² and runs its own in-house production line. Mixing, filling and packaging happen under one roof, which gives us direct control over consistency from batch to batch. Formulations are developed and checked in a 2,000 m² R&D testing center, and our manufacturing holds BRI certification. OEM and ODM programs are available for partners who want our formulas under their own brand.
Two compounds, one clear system
S8 is made for sheet metal and paint, with an 8 cutting / 8 light rating for the step after sanding. S9 is universal fit for all car series and all car paint types, rated 9 cutting / 9 light. Pair S9 with different pads and one bottle covers the heavy and medium steps that traditionally meant buying heavy, medium and fine compounds. A deep mirror finish is optional. Both compounds work with the same simple method: sandpaper, polishing pad, compound.
Why we sell direct
Buying from the manufacturer means fewer steps between the production line and your polishing pad. It also means the product pages can tell you exactly what a compound is rated for instead of hiding behind vague claims. We publish the cutting and light ratings, the sizes and the process, and we let the before-and-after results show the rest.
Who we make it for
Car enthusiasts who want a better finish at home. Detailers who want a reliable compound for everyday jobs. Body-shop professionals who need consistent results and sizes that match their workload. Orders ship worldwide, with a 30-day return and exchange policy and secure checkout.

What we stand for
Honest products, clear instructions and support that answers. Results depend on the surface, the pad and the technique, so we say that up front. We would rather set the right expectation than make a promise that does not hold up in the shop.
