THE FINISHER × Koch-Chemie – no-compromise system care for automotive and marine

What makes THE FINISHER special? — The line brings precise Koch-Chemie formulations together into one clear, coordinated system for paint, glass, interior, gelcoat & vinyl – results you feel fast, easy application, a reliable routine for road and water.

THE FINISHER is our curated detailing line built on proven Koch-Chemie technology – put together to give you a logical, hands-on care routine for automotive and marine. From a safe pre-wash to a high-gloss finish the products work into each other: you work faster, dodge the usual application mistakes and hit repeatable results on paint, glass, plastics, leather, fabric and on gelcoat and boat deck. Care stops feeling like an experiment and starts feeling like a system – on land just as much as on the water.

• A system, not a patchwork: cleaners, polishes, shampoos and sealants are matched to each other – for clean processes, less mixing of brands and results you can count on.
• Efficiency you can see and feel: strong cleaning power, excellent glide and wipe-off, stable beading – with clear, simple working steps.
• Two worlds, one logic: dedicated solutions for automotive surfaces and marine demands (salt, UV, gelcoat), with the same intuitive handling.

Automotive detailing – from pre-wash to high gloss

Automotive detailing starts with a safe pre-clean, runs through material-friendly interior care and ends in a hard-wearing paint finish. For glass, ClearView and DisplayExpert give you streak-free vision and gentle infotainment cleaning; inside, InsideUp (cleaning) and InsideCare/InsideCare (conditioning) work hand in hand. Outside you lay the base with InsectOff and pH-neutral foams like TropicSnow before MagicShampoo tops up gloss and protection. Wheels? WheelKing lifts brake dust reactively and acid-free. For a quick shot of gloss you reach for JustPerfect as a quick detailer – perfect right after the wash. On paint defects, our stepped polishes – RoughCut/FineCut, PowerSpeedPolish or ShineSpeedPolish – bring clarity back to the surface; then a spray or wax finish locks the work in. What you get is a closed, smooth workflow from the first spray to the final buff-off.

Marine detailing – gelcoat, vinyl & deck under control

Marine detailing plays by its own rules: salt, UV and large gelcoat areas call for products with real staying power at sea. CleanMarine lays the clean base as a universal boat shampoo. On windows and polycarbonate, SeaYou goes to work – formulated for clear vision with no smearing. VinylTexClean pulls dirt out of upholstery deep in the pores; VinylGuard conditions and protects with a nice feel in the hand. RubMarine freshens up unpainted plastics and rubber, silicone-free. For the big paint and gelcoat show we've got the stepped polish chain: RoughCut (step 1) for deeper defects, FineCut (step 2) for holograms and streaks, PerfectOne as a powerful one-step or WaxPolish as a classic hard-wax finish. BodyGuard rounds it off with a hydrophobic spray sealant; HelloWhite visibly brings yellowed areas back and CoverGuard protects fabrics on board for the long haul. The upshot: smooth surfaces, easier cleaning, clean water run-off – and a cockpit that still looks fresh after long trips.

Application & workflow – clear steps, low risk

System care means you work by material, cleanly split into steps and with the right tools. Outside you always start cool (no hot surfaces), never let chemistry dry on and rinse thoroughly. Give reactive wheel cleaners their dwell time and back them up mechanically with brushes – then rinse off with pressure. Lay foam shampoo or pre-cleaner on across the panel to encapsulate dirt; on the hand wash the care shampoo gives you glide and protects any sealant already there. Run polishes panel by panel in a cross pattern, match pad hardness and cut to the defect and buff residue out completely. Inside you work "dirty to clean": cleaner first (InsideUp, LeatherTexClean, VinylTexClean), then conditioner (InsideCare/InsideCare, LeatherLock, VinylGuard); clean sensitive displays separately with DisplayExpert. On the boat the prep (degrease, dry) is what counts before you apply BodyGuard or CoverGuard – that's how the hydrophobicity and the easy-to-clean effect hold noticeably longer.

Common questions about THE FINISHER

Who is THE FINISHER from Koch-Chemie for?
For ambitious enthusiasts and pros who want a well-thought-out, fast workflow with repeatable results on vehicles and boats – without a jungle of products.

How does automotive differ from marine?
Marine products are optimised for gelcoat, vinyl, UV and salt-water exposure. Automotive covers paint, glass, wheels and interior in everyday road use – both worlds follow the same simple logic.
