What's InsideCare for? — This interior care feeds and protects plastic, rubber and vinyl after cleaning, lays down a satin-matte OEM finish, works anti-static and leaves a dry, non-greasy feel – in car and boat.
THE FINISHER InsideCare interior care is your material-friendly care for the cockpit, door cards, consoles, rubber seals and vinyl surfaces. It brings colour depth back, cuts dust pickup thanks to anti-static additives and gives a calm, satin-matte look with no greasy shine. In automotive interiors InsideCare brings textured parts back out evenly; on the water it stabilises vinyl and plastic against the usual hits like salt, UV and constant wiping. Important: always-on in the system – after cleaning with InsideUp, lay it down, then add LeatherLock (leather) or VinylGuard (vinyl) depending on the material.
Interior care means: conditioning surfaces after cleaning without faking the feel. THE FINISHER InsideCare works with nourishing polymers and additives that flash off evenly and leave a satin-matte, near-OEM finish. Heavy-gloss dressings often look out of place in modern interiors; here InsideCare deliberately gives you a restrained look with a defined grip. On textured plastics the product spreads homogeneously, so matte areas don't go blotchy. Vinyl gets a fresh, rich look without smearing. Rubber seals look better and stay supple. The order matters: clean first (InsideUp), then care (InsideCare) and only protect on top when you need to (e.g. VinylGuard on vinyl). Displays, piano black and glass aren't a job for interior care – that's what DisplayExpert and ClearView are there for.
Automotive surfaces live on a calm look and a dry feel. Work panel by panel: put InsideCare thinly onto a soft applicator pad or microfibre, spread it evenly and let it flash off for 1–2 minutes. Then wipe gently with a clean side of the cloth until the surface looks evenly satin-matte. Keep it off the steering wheel, gear knob and pedals – there a plain clean (InsideUp) is enough, because grip is what counts. On badly faded plastics you can repeat the coat once it's fully flashed off. After care dust comes off more easily and fingerprints show up less. For leather the line stays clear: clean with InsideUp or target it with LeatherTexClean, then care with LeatherLock. Clean textiles separately and protect them optionally with TexLock – InsideCare doesn't belong on fabric.
Marine environments need care that feels tough and is easy to top up. On boat vinyl, console and cabin plastics you use InsideCare after a thorough clean with InsideUp. The product lays down thin and even, cuts that typical salt-haze look and gives a rich, non-greasy surface. Work in the shade on cool materials – direct sun or hot surfaces shorten the flash-off time and can lead to patchy results. Upholstery and large vinyl that's more exposed you can lock in with VinylGuard if needed; that keeps cleaning easier and the feel consistent for longer. InsideCare isn't meant for gelcoat exteriors – out there you reach for CleanMarine, the polishing chain (RoughCut/FineCut/PerfectOne) and finally BodyGuard for the hydrophobic protection. In the cabin: glass with SeaYou, clean textile surfaces first then optionally protect with CoverGuard/TexLock – InsideCare stays on the hard interior surfaces.
To plastic, vinyl and rubber inside. Don't use it on glass, piano black, pedals/steering wheel or textile. Leather you care for after cleaning with LeatherLock.
Put it thinly on a pad/cloth, spread evenly, let it flash off briefly and wipe gently with a clean side. Don't work in the sun, and don't drown the surface in product.
No. It gives a satin-matte, near-OEM look with a dry feel – no greasy film and no shiny patches.
Yes, ideal for vinyl and plastic surfaces in the cockpit and cabin. After cleaning with InsideUp lay it down thin, buff it off evenly; lock in exposed vinyl with VinylGuard if you like.
Depends on use and cleaning. In the car usually every 4–8 weeks, on board after hard trips or thorough cleans. Work thin and even, without building up layers.
