Trim Restoration

Bring faded plastics back to life, without the grease

Why Plast Star

Four reasons it earns a place in every detailing bay

Silicone-oil-free trim care built for professional results

  • Micro-Emulsion Bonding

    The unique micro-emulsion system bonds firmly to plastics and rubber rather than sitting on top.

  • UV and Weathering Shield

    Delivers months of protection against UV fade and outdoor weathering on exposed trim.

  • Zero Greasy Residue

    Silicone-oil-free formula leaves a clean, semi-matt finish that won't attract dust or contaminate paint.

  • Seal Protection

    Keeps door seals supple and prevents freezing, extending the life of rubber components.

How It Compares

Plast Star Siliconolfrei vs a typical trim dressing

Most trim dressings do a basic job of darkening faded plastics. Here is where the silicone-oil-free formulation and micro-emulsion system make a real difference for professional work.

Thabo K. Verified

The trim on a black BMW I work on regularly goes grey after a few months of Joburg sun. Two wipes with this and it looks like a different vehicle - no shine, just a clean, factory-dark look. Exactly what I want.

Aneesa H. Verified

Decent product. The semi-matt result is spot on and there's genuinely no grease or drip onto the paint. I do have to work it in properly - lazy application shows uneven coverage, but that's on the user.

Yusuf R. Verified

Running this through my workshop on every full detail now. The 10L lasts well and the silicone-free formula means I can dress the trim before or after ceramic work without any fisheye drama.

Mbali N. Verified

Tried it on badly faded rear bumper plastics on a bakkie that sits outside all week. Came up beautifully. No greasy smear, just solid, even coverage. Happy with the longevity so far.

Imraan G. Verified

What sold me is the silicone-oil-free spec. I coat a lot of cars and the last thing I need is contaminated panels from trim dressing migration. This is the one I've been looking for. Packaging arrived intact from Detailer SA, which is always appreciated on a 10L.

Palesa J. Verified

Pleasant fragrance makes a difference when you're working in an enclosed bay. Product itself is good - protection holds up well and the finish doesn't go shiny or attract dust. Would buy again.

Rashied B. Verified

Door seals on my sedan were starting to look rough and I was worried about them cracking in winter. Regular treatment with this has kept them supple and they haven't given me any trouble.

Kavita P. Verified

Not a heavy gloss, which is exactly what exterior plastics should look like. It restores the colour without making it look like you've poured tyre shine over everything. Solid trim care.

Questions

Frequently asked

How do I apply Plast Star Siliconolfrei to exterior trim?

Apply to clean, dry trim using a foam or microfibre applicator pad. Work the product evenly into the surface, let it bond briefly, then wipe off any excess with a clean microfibre cloth. For heavily faded trim, a second pass once the first has set can deepen the restoration.

Which surfaces is this product compatible with?

Plast Star Siliconolfrei is designed for exterior plastics and rubber - bumper covers, unpainted trim strips, door mouldings, weather seals and rubber gaskets. It is not intended for paint, glass or coated surfaces. Keep it off lacquered or painted panels during application.

Will it leave a greasy or shiny finish on my trim?

No. The silicone-oil-free formula leaves a semi-matt, natural-looking finish that matches the OEM appearance of most exterior plastics. There is no oily residue that attracts dust or drips onto paintwork.

How long does the protection last?

The product is formulated to provide months of protection against UV damage, fading and weathering. Longevity will depend on how much sun and rain the vehicle is exposed to, but regular application is straightforward given how easy it goes on.

Why is it better for detailers to use a silicone-oil-free formula?

Silicone oils can migrate onto adjacent paint and glass surfaces, causing fisheye issues if you polish or coat nearby panels afterward. A silicone-oil-free product eliminates that contamination risk entirely, which is especially important when dressing trim as part of a full correction or ceramic coating job.

Can I use this product to prevent door seals from sticking or freezing?

Yes. One of the stated functions of Plast Star Siliconolfrei is preventing door seals from freezing, which is useful for vehicles kept outdoors in colder conditions such as the Highveld winter or high-altitude areas. Regular treatment of door rubbers keeps them supple and reduces freezing.

What coverage can I expect from the 10L container?

Coverage depends on how much trim area each vehicle has and how the product is applied, but a 10L container is sized for professional workshop use - expect it to cover a substantial number of vehicle treatments. For a single-car owner, the 10L is a trade-size buy suited to detailers with ongoing client volume.

Can I apply Plast Star Siliconolfrei on top of or under a ceramic coating?

It is best used on uncoated trim. If your trim panels carry a ceramic coating, check that the dressing is compatible with that coating first. Because it is silicone-oil-free, it will not interfere with paint-side ceramic work happening at the same time, which is its main advantage in a full-detail workflow.
