Engine Bay Care
Motorplast lays down a water-displacing, permanently elastic film across rubber hoses, housings and metal components - protecting against corrosion and environmental fallout while leaving a naturally shiny, factory-fresh appearance.
Why Motorplast
Four reasons professionals reach for Motorplast in the engine bay.
The elastic protective film seals out moisture and environmental contaminants that cause rust on metal housing parts.
Repels water on contact and dries to a clean finish that does not trap dust or road grime.
Formulated to stay stable under the high temperatures generated by engines and power units.
Manufacturer approval confirms Motorplast meets the standards required for commercial and passenger vehicle use.
How it stacks up
Not all engine dressings are built the same. Here is how Motorplast compares to a typical budget alternative on the features that matter in a professional engine bay detail.
| Feature | DetailerSA | Alternative |
|---|---|---|
| Dry, non-greasy finish | Yes | No |
| Temperature resistance to 250°C | Yes | No |
| Suitable for wet and dry surfaces | Yes | Yes |
| Manufacturer (Daimler) approval | Yes | No |
| Corrosion protection on metal parts | Yes | Yes |
| Safe on rubber hoses and seals | Yes | Yes |
Built for Professionals
Unlike silicone-heavy dressings that attract grime, Motorplast dries to a completely clean film - making it the right choice for engine bays where a dust-attracting residue is a problem. Temperature resistance to 250°C and Daimler approval back that up.
Reviews
Engine bay on the Sprinter looks brand new. The finish is natural - not the wet, artificial look you get from cheap silicone sprays. Dried clean and no dust sticking after a week of daily driving.
Good product for rubber hoses and plastic housings. Takes a couple of minutes to dry properly but the result is a tidy, uniform sheen. Would be five stars if it came in a larger size.
Three coats of this over the last few months and the rubber hoses under the bonnet still look conditioned. No cracking, no fading. Koch-Chemie quality you can count on.
Clean dry finish, no oily residue at all. Exactly what you want in an engine bay - anything greasy just collects dust and defeats the purpose of detailing.
Solid engine conserver. Picked it up with a few other Koch-Chemie products and arrived well-packaged. Works well on the plastic covers and rubber seals - subtle sheen, not overdone.
Customer brought in a fleet bakkie with a dry, cracked engine bay. After decon and a coat of Motorplast the rubber hoses looked restored. The dry film meant no dust had settled by the time they collected it.
Questions
Motorplast is formulated for engine bays, rubber hoses, plastic and metal housing parts, and power units on passenger cars and commercial vehicles. It is safe on both rubber and hard plastic components.
Yes. Motorplast is suitable for use on both dry and wet surfaces, so you can apply it directly after a rinse without waiting for the bay to dry completely.
Spray an even, thin film onto pre-cleaned surfaces using a spray bottle or the Koch-Chemie Cyclone applicator. Leave the product to dry fully - no wiping or buffing is required. The result is a clean, naturally shiny finish.
No. The formulation dries to a complete dry finish with no lubricating film. This is important in an engine bay - an oily residue would attract dust and grime, and could be a safety concern near hot components. The dry film actively resists dirt adhesion.
Motorplast is temperature-resistant to 250°C, making it suitable for use on and around engine components that generate significant heat during operation.
Yes. The permanently elastic protective film forms a barrier against moisture, environmental fallout and corrosion. This is particularly useful on metal housing components and exposed engine parts in harsh driving conditions.
Motorplast carries official Daimler approval, confirming it meets the standards required for use on Mercedes-Benz and related vehicles. It is also suitable for general use on most passenger cars and commercial vehicles.
Yes. Once the previous application has fully dried, you can reapply Motorplast to refresh the protection and appearance. There is no cure window to manage - simply clean the surface, spray, and leave to dry.
