Koch Chemie Motorplast

A clean engine bay does not just look well cared for, it also protects components against corrosion and ageing. Koch Chemie Motorplast is a water-displacing preservative for engines, housings, and rubber hoses on cars and commercial vehicles, with a pleasant scent. The product dries completely without leaving a greasy film, so new dirt sticks less easily. Thanks to the permanently elastic protective layer, parts are shielded against corrosion and environmental influences, on both dry and wet surfaces. Motorplast is heat-resistant up to 250 degrees Celsius and carries Daimler approval. Apply the product with a cloth or spray bottle to a cleaned engine bay, and let it dry fully for a naturally glossy, well-kept result. It also suits commercial vehicles and workshops with heavier use, where parts face extra exposure to heat, moisture, and road grime. Regular treatment keeps the engine bay looking cared for longer and better protected against everyday wear.
