THE FINISHER × Koch-Chemie „InsideCare“ — Interior Care with a Natural OEM Finish

What is InsideCare for? — This interior care product nourishes and protects plastic, rubber, and vinyl after cleaning, creates a silky matte OEM finish, has an antistatic effect, and leaves a dry, non-greasy feel – in cars and boats.

THE FINISHER InsideCare Interior Care is your material-friendly care for dashboards, door panels, consoles, rubber seals, and vinyl surfaces. It refreshes color depth, reduces dust attraction with antistatic additives, and ensures a calm, silky matte appearance without a greasy shine. In automotive interiors, InsideCare brings structural parts back to an even appearance; in a marine context, it stabilizes vinyl and plastic surfaces against typical stresses such as salt, UV, and frequent wiping. Important: Always-on in the system – apply after cleaning with InsideUp, then supplement with LeatherLock (leather) or VinylGuard (vinyl) depending on the material.

• Silky matte OEM finish: Uniform color depth without glossy spots; pleasant, dry feel for grippy controls.
• Antistatic & nourishing: Reduces dust attraction, visually refreshes brittle-looking plastics, and facilitates ongoing care.
• System compatible: Perfect step after InsideUp; harmonizes with LeatherLock (leather), VinylGuard (vinyl), and TexLock (textile protection – do not apply, only supplement).

Interior Care – Technology, Finish & Material Understanding

Interior care means: conditioning surfaces after cleaning without distorting the feel. THE FINISHER InsideCare works with nourishing polymers and additives that evaporate evenly and leave a silky matte, OEM-like finish. Highly glossy dressings often look out of place in modern interiors; InsideCare deliberately delivers a subtle look with defined grip here. On textured plastics, the product distributes homogeneously, so that matte areas do not appear patchy. Vinyl gets a fresh, rich appearance without smearing. Rubber seals benefit visually and remain supple. The order is important: first clean (InsideUp), then care (InsideCare), and only protect additionally if necessary (e.g., VinylGuard on vinyl). Displays, piano lacquer, and glass are not areas of application for interior care – DisplayExpert and ClearView are available for these.

Automotive – Apply, Buff, Secure Feel

Automotive surfaces thrive on visual calm and a dry feel. Work component by component: apply InsideCare thinly to a soft applicator pad or microfiber cloth, distribute evenly, and allow to flash off for 1–2 minutes. Then gently wipe with a clean side of the cloth until the surface appears uniformly silky matte. Do not apply to the steering wheel, gear knob, and pedals – pure cleaning (InsideUp) is sufficient there, as maximum grip is crucial. For severely faded plastics, you can repeat the layer after complete flashing off. After care, dust is easier to remove, and fingerprints are less pronounced. For leather surfaces, the line remains clear: clean with InsideUp or specifically with LeatherTexClean, then care with LeatherLock. Clean textiles separately and optionally protect them with TexLock – InsideCare does not belong on fabric.

Marine – Vinyl & Plastics in the Cockpit and Cabin

Marine environments require care that is robust and easy to renew at the same time. On boat vinyl, console, and cabin plastics, use InsideCare after thorough cleaning with InsideUp. The product applies thinly and evenly, reduces the typical salt film look, and provides a rich, non-greasy surface. Pay attention to shaded processing and cool materials – direct sun or hot surfaces shorten the flashing off time and can lead to uneven results. Upholstery and large vinyl surfaces that are more exposed can be additionally protected with VinylGuard if necessary; this makes cleaning easier and the feel remains consistent for longer. InsideCare is not intended for gelcoat exteriors – CleanMarine, the polishing chain (RoughCut/FineCut/PerfectOne), and finally BodyGuard for hydrophobic protection are used there. In the cabin: use SeaYou for glass, clean textile surfaces first, then optionally protect with CoverGuard/TexLock – InsideCare is reserved for hard interior surfaces.
