THE FINISHER × Koch-Chemie – uncompromising system care for automotive and marine

What makes THE FINISHER special? — The line combines precise Koch-Chemie formulations into a clear, coordinated system for paint, glass, interior, gelcoat & vinyl – quickly noticeable results, easy application, reliable routine for road and sea.

THE FINISHER is our curated detailing line based on proven Koch-Chemie technology – developed to give you a logically structured, practical care routine for automotive and marine. From safe pre-wash to high-gloss finish, the products work together: you work faster, avoid typical application errors, and achieve reproducible results on paint, glass, plastics, leather, textiles, as well as on gelcoat and boat deck. This way, care feels like a system, not an experiment – on land as well as on water.

• System approach instead of patchwork: Cleaners, polishes, shampoos, and sealants are coordinated – for clean processes, less material mix, and reliable results.
• Efficiency that can be seen and felt: Strong cleaning performance, excellent glide and polishing properties, stable beading effects – with clear, simple steps.
• Two worlds, one logic: Special solutions for automotive surfaces and marine requirements (salt, UV, gelcoat), with the same intuitive handling.

Automotive Detailing – from pre-wash to high gloss

Automotive Detailing begins with a safe pre-cleaning, continues with material-appropriate interior care, and ends with a durable paint finish. For glass, ClearView and DisplayExpert ensure streak-free vision and sensitive infotainment cleaning; in the interior, InsideUp (cleaning) and InsideCare/InsideCare (care) work hand in hand. On the exterior, you lay the foundation with InsectOff and pH-neutral foams like TropicSnow before MagicShampoo reloads gloss and protection. Rims? WheelKing removes brake dust reactively and acid-free. For a quick gloss boost, use JustPerfect as a quick detailer – ideal after washing. For paint defects, our graded polishes – RoughCut/FineCut, PowerSpeedPolish, or ShineSpeedPolish – restore clarity to the surface; then a spray or wax finish fixes the work. This creates a closed, smooth workflow from the first spray to the final polishing.

Marine Detailing – Gelcoat, Vinyl & Deck under control

Marine Detailing has its own rules: salt, UV, and large gelcoat areas demand products with marine endurance. CleanMarine provides a clean base as a universal boat shampoo. On windows and polycarbonate, SeaYou works – formulated for clear vision without streaks. VinylTexClean deeply cleans upholstery; VinylGuard cares for and protects with a pleasant feel. Unpainted plastics and rubber are refreshed silicone-free with RubMarine. For the big paint and gelcoat show, we offer a graded polishing chain: RoughCut (Step 1) for deeper defects, FineCut (Step 2) for holograms and swirls, PerfectOne as a powerful one-step solution, or WaxPolish as a classic hard wax finish. BodyGuard rounds it off with hydrophobic spray sealant; HelloWhite visibly brightens yellowed areas, and CoverGuard protects textiles on board long-lastingly. Result: smooth surfaces, easier cleaning, clean beading – and a cockpit that looks fresh even after long cruises.

Application & Process – clear steps, low risk

System care means: you work according to material, cleanly separated by work steps and with suitable tools. On the exterior, you always start cold (no hot surfaces), never let chemicals dry, and rinse thoroughly. For reactive wheel cleaners, allow dwell time and assist mechanically with brushes – then rinse off with pressure. Apply foam shampoo or pre-cleaner over the surface to encapsulate dirt; for hand washing, the care shampoo provides lubrication and protects existing sealants. Apply polishes panel by panel in a cross-hatch pattern, matching pad hardness and cut to the defect, and fully polish away residues. Inside, work from "dirty to clean": first cleaners (InsideUp, LeatherTexClean, VinylTexClean), then care products (InsideCare/InsideCare, LeatherLock, VinylGuard); sensitive displays are cleaned separately with DisplayExpert. On the boat, preparation (degreasing, drying) is crucial before BodyGuard or CoverGuard are applied – this way, hydrophobicity and the easy-to-clean effect last noticeably longer.
