Koch Chemie PSS Plast Star - plastic and rubber protection

Koch-Chemie PSS Plast Star (siliconölfrei) is a professional exterior plastic and rubber dressing designed to restore colour depth while providing long-term protection. The silicone-oil-free formulation makes it suitable for bodyshop environments and modern OEM requirements.

PSS penetrates porous plastic and rubber surfaces, revitalising faded trim and leaving a rich satin finish. The advanced UV inhibitors help prevent premature fading and cracking caused by environmental exposure.

Restores faded exterior plastics

Finish Characteristics

PSS produces a deep, natural satin appearance rather than an artificial high gloss. It darkens and enriches trim without leaving a greasy surface when applied correctly. When applied to properly cleaned surfaces, Plast Star offers long-lasting weather resistance and wash durability, making it suitable for both enthusiast and professional use.

Application

Clean plastic or rubber thoroughly before application.
Apply sparingly using a foam applicator.
Allow to absorb into the surface.
Buff lightly if required to level the finish.

Professional Guidance

Apply thinly to avoid excess residue.
Do not apply to tyre tread or braking surfaces.
Allow sufficient curing time before exposure to rain.

Koch-Chemie PSS Plast Star is ideal for detailers seeking controlled, professional trim restoration with OEM-level finish quality.

Our Take

“Why this remains one of our go-to trim dressings for long-lasting, professional results.”

Plast Star Siliconölfrei (PSS) is exactly what we’ve come to expect from Koch Chemie — properly engineered, German-manufactured chemistry that focuses on performance rather than gimmicks. It’s silicone-free, which makes it ideal for professional environments, but what keeps us using it is the finish and longevity.

In terms of appearance, we get a rich, even darkening on plastics and rubber without that greasy, over-dressed shine. It restores depth to faded trim while still looking appropriate and refined. On modern vehicles especially, that understated OEM-style finish is what we prefer.

Durability is strong when applied to clean, dry surfaces. It holds up well to weather and regular washing, meaning we’re not constantly reapplying after a few weeks. We’ve found it particularly effective on exterior plastics, arch trims, and rubber seals where longevity actually matters.

The 1 litre bottle also represents excellent value. It goes a long way, especially when applied thinly, and for us that combination of quality manufacturing, consistent performance, and sensible pricing makes it very hard to overlook.

If we want a trim dressing that’s professional-grade, silicone-free, and built to last, PSS is a very easy recommendation.

What is Koch Chemie PSS Plast Star and what is it designed to do?

Koch Chemie PSS Plast Star is a professional silicone-oil-free plastic and rubber dressing specifically designed to restore colour depth to faded exterior trim while providing long-term protection.

How should I apply Koch Chemie PSS Plast Star for best results?

Clean the plastic or rubber surface thoroughly before application. Apply PSS Plast Star sparingly using a foam applicator, allowing it to absorb into the surface. Buff lightly if required to level the finish. Apply thinly to avoid excess residue and never apply to tyre tread or braking surfaces. Allow sufficient curing time for optimal durability.

It's suitable for all exterior plastic and rubber components including bumper trim, door seals, wing mirrors, and other weathered plastic parts. The advanced UV inhibitors provide ongoing protection against environmental exposure that causes fading and cracking.
