A ready-to-use wet coat sealant on a polysiloxane base that you spray straight onto wet paint after the wash and rinse off with the pressure washer. Three to six weeks of measurable beading per application, no buffing. Not suitable for matte paint, matte wraps, fabric soft tops or fresh paintwork under 30 days old.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eKoch-Chemie WetGloss\u003c\/strong\u003e is a ready-to-use wet coat sealant from Koch-Chemie in Unna that goes on right after the wash with no polishing or wiping step. The active ingredient is an amino-functional polysiloxane — in plain terms, a flexible silicone polymer with two different ends. One end carries nitrogen anchors (amino groups), the other water-repellent methyl groups. On wet paint the polymer lines itself up on its own: anchors into the clear coat, methyl ends facing out. What that means for you: the water beads straight off in tight little balls instead of clinging to the paint — no carnauba wax, no silicon dioxide like a ceramic coating, just a self-aligner that holds for three to six weeks.\u003c\/p\u003e\n\n\u003cp\u003eDetailers call this workflow \"spray-on, rinse-off\": spray it on, rinse it off, done. You lay the WetGloss down section by section on the wet car right after rinsing off the shampoo, the pressure washer spreads the polymer evenly across the section in seconds, and the excess runs off with the rinse water. Drying with the microfibre towel is the only moment you still touch the paint. Handy: it works as a standalone sealing step between full details — and as a topper over existing ceramic or wax coatings, freshening the hydrophobics so you can hear it and visibly tightening up the way water beads off.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-wet-gloss-wg-nassversiegelung_hero.png?v=1778700765\" alt=\"Applying Koch-Chemie WetGloss Wg 500 ml on a black Porsche 911\" loading=\"lazy\" style=\"max-width:100%;height:auto;\"\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBeading refresh in minutes.\u003c\/strong\u003e Straight after the rinse, water beads off the paint in tight, compact drops instead of forming a flat film — that classic showroom-fresh effect. Day-to-day you'll see it from the first drive in the rain, and the next time you dry the car you'll go through half the microfibre. It saves you the wipe-and-flip dance of a dry spray sealant and the slog of buffing off a carnauba wax.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThree to six weeks of protection per application.\u003c\/strong\u003e On the typical commuter routine with a wash every two to four weeks, the polymer layer runs right through to the next refresh. The 500 ml spray bottle covers three to five mid-size cars when you work section by section — about 2.30 to 5.10 euros per seal. The 5-litre canister pays off from the second car in the household or in commercial use.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReady to use, no diluting, no foam lance.\u003c\/strong\u003e Unlike the Hydro Foam Sealant S0.03, which gets diluted 1:50 to 1:150 through a foam lance, or the Spray Sealant S0.02, which needs 20 minutes of buffing once it's flashed off, the WetGloss only asks for a spray bottle, a pressure washer and a microfibre towel. What that means for you: the whole sealing step fits into a single bay slot at the self-service wash.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDay-to-day from Detailing1:\u003c\/strong\u003e The costliest mistake with the WetGloss is letting it flash off on paint that's too warm. Once a panel hits roughly 30 to 40 degrees — which dark paint reaches within minutes in May sunshine — the alcohol carrier solvent (2-propanol, technically) evaporates so fast that the polymer cross-links unevenly. In plain terms: the amino-functional polysiloxane only grabs the paint in patches and leaves white streaks or water spots in the bits it didn't cover. Worst case you have to pull the residue off with an alkaline cleaner or even a light machine polish — half an hour of extra work the application was meant to save you. So always work in the shade, on a cool body under 25 degrees and section by section: spray the bonnet, rinse it straight away, then move to the next section. The pressure washer is a must. Its hard jet drops the consumption from the 250 millilitres the maker quotes defensively to a realistic 100 to 150 millilitres per mid-size car.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eApplying WetGloss properly: wet paint, section, high pressure\u003c\/h3\u003e\n\n\u003cp\u003eYou spray the Koch-Chemie WetGloss section by section onto the wet car right after the wash, rinse straight away with high pressure and dry with the microfibre towel. Three steps, no buffing.\u003c\/p\u003e\n\n\u003cp\u003eThe running order in practice: car pre-washed, foam rinsed off, body still dripping wet. You grab the spray bottle, give it a quick shake and work in sections — half the roof, one wing, one door area. Six to eight pumps per section is plenty, no flooding it. Straight after, rinse off with the pressure washer from about 30 centimetres, top to bottom, until the water rolls off in tight drops and no foam streaks run down any more. Only then move to the next section.\u003c\/p\u003e\n\n\u003cp\u003eThe rinse pressure makes or breaks the result. A plain garden hose won't cut it: the polymer won't spread evenly and you'll burn through twice as much for half the result. You want over 100 bar, the kind every self-service wash box delivers. With hard tap water, dry straight after the final rinse — leftover water otherwise leaves limescale spots on the freshly sealed surface.\u003c\/p\u003e\n\n\u003cp\u003eFor drying, a soft microfibre drying towel pulled across in sections does the job. In day-to-day Detailing1 work it runs best out of the \u003ca href=\"\/en\/collections\/koch-chemie\"\u003eKoch-Chemie range\u003c\/a\u003e in the order wash, wheel cleaning, WetGloss, dry — the whole exterior workflow on a mid-size car comes in under 25 minutes.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-wet-gloss-wg-nassversiegelung_anwendung.png?v=1778700773\" alt=\"Spraying Koch-Chemie WetGloss Wg 500 ml onto a wet bonnet\" loading=\"lazy\" style=\"max-width:100%;height:auto;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eAminosilane fixes no paint defects and masks your coating temporarily\u003c\/h3\u003e\n\n\u003cp\u003eThe WetGloss is not a substitute for a paint correction and not a multi-year protection layer — it tops up your routine between full details with beading you can measure right away. If you want to take out scratches or buff away holograms, you're in the wrong place.\u003c\/p\u003e\n\n\u003cp\u003eThe clear no-go substrates. Matte paint and matte wraps get optically smoothed over by the polymer, leaving an unwanted greasy look — the maker rules this use out explicitly, and the only way back out of that effect is an alkaline cleaner. Fabric soft tops soak the emulsion up unevenly and stiffen the fibres; there are dedicated textile sealants for those. Fresh paintwork under 30 days old needs time to off-gas — a seal on top can slow the curing and, worst case, lead to clouding. Bare polished aluminium can streak depending on the alloy, because the raw metal binds the polymer's nitrogen anchors differently than a closed clear coat.\u003c\/p\u003e\n\n\u003cp\u003eThe second, less well-known behaviour is the masking effect: lay WetGloss over an existing ceramic coating with pronounced sheeting behaviour — that is, water rolling off flat rather than forming drops — and for three to six weeks the polymer takes over the water behaviour of the seal. Your SiO₂ coating's flat sheeting turns into beading. In practice: the coating isn't harmed, and once the sacrificial layer washes off the original behaviour comes back. But if you've only just had a premium coating built up, be aware of the temporary change in character and use it more as a winter refresh.\u003c\/p\u003e\n\n\u003cp\u003eThe choice logic within the Koch-Chemie range. If you want a touch-free refresh in minutes between washes → WetGloss. If you want maximum durability on dry paint and you'll take the manual buffing → \u003ca href=\"\/en\/products\/koch-chemie-spray-sealant-s0-02-spruehversiegelung\"\u003eSpray Sealant S0.02\u003c\/a\u003e.

If you want a snow foam concentrate with foam-lance dilution 1:50 to 1:150 for the workshop → the Hydro Foam Sealant S0.03 is the better tool.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-wet-gloss-wg-nassversiegelung_ergebnis.png?v=1778700782\" alt=\"Tight beading after sealing with Koch-Chemie WetGloss Wg 500 ml\" loading=\"lazy\" style=\"max-width:100%;height:auto;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eFor maintenance-interval detailers, not for the full reconditioning job\u003c\/h3\u003e\n\n\u003cp\u003eThe WetGloss is the right call for anyone who washes their paint every two to four weeks and wants to build up visible protection between sessions. After the regular hand wash you reach for the spray bottle, six pumps per section, rinse, dry — five minutes of extra work for four to six weeks of measurable hydrophobicity.\u003c\/p\u003e\n\n\u003cp\u003eIt's especially economical in a multi-car household and in small commercial use. At a realistic consumption of 100 to 150 millilitres, the 5-litre container covers more than 33 seals. Run the WetGloss alongside a regular foam pre-wash and you stretch the effective durability even further, because the polymer doesn't have to break down any heavy crust and can build cleanly onto a well-kept surface.\u003c\/p\u003e\n\n\u003cp\u003eThe WetGloss is less suited to reconditioners with a snow foam lance who have to run bigger fleets touch-free — there the concentrated Hydro Foam Sealant S0.03 wins on cost per application. And for paint-shop handovers with fresh repair paintwork, the 30-day waiting window applies, no exceptions.\u003c\/p\u003e\n\n\u003cp\u003eThe one trick the maker doesn't say out loud: don't spray the whole car at once. Lay one section down, pull the water film over it straight away with high pressure, then on to the next. In plain terms: the polymer only needs the seconds in which the hard jet pushes the material across the wet panel — that's exactly where the cross-linking happens, before the alcohol carrier solvent evaporates and can leave streaks. What that means for you: two applications per 500 ml bottle become four to five, the real per-litre cost halves, and you still get measurably tighter beading than spraying the whole car in one go.\u003c\/p\u003e\n\n\u003cp\u003eStore frost-free between 5 and 30 degrees, shake before use. On the compliance side: because of the classification \"harmful to aquatic life\" (H412 under GHS), only work with it on a wash bay with an oil separator. A private driveway with a direct connection to the rainwater drain is off-limits under environmental law in the DACH region — so the trip to the self-service wash box or the commercial detailing park isn't just convenience, it's a must.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-wet-gloss-wg-nassversiegelung_lineup.png?v=1778700790\" alt=\"Koch-Chemie WetGloss Wg 500 ml on the workbench in the workshop\" loading=\"lazy\" style=\"max-width:100%;height:auto;\"\u003e\u003c\/p\u003e","brand":"Koch-Chemie","offers":[{"title":"500ml","offer_id":57637110317391,"sku":"D1-KCX-684500","price":18.14,"currency_code":"EUR","in_stock":true},{"title":"5 liters","offer_id":57637057331535,"sku":"D1-KCX-684005","price":80.66,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-wet-gloss-wg-nassversiegelung.png?v=1778655969","url":"https:\/\/detailing1.fr\/en\/products\/koch-chemie-wet-gloss-wg-nassversiegelung","provider":"Detailing1","version":"1.0","type":"link"}
