Koch-Chemie Plast Star PS — Exterior Plastic & Tire Care, 1 L

Premium Exterior Trim & Rubber Sealant with Daimler Approval

Koch-Chemie Plast Star PS is the benchmark solvent-based exterior dressing formulated for lasting rejuvenation of weathered unpainted bumpers, side mirror housings, trim mouldings, and rubber weatherstripping. Backed by official Daimler approval, Plast Star bonds molecularly to polymer surfaces to prevent grey chalking, environmental weathering, and winter door seal freeze-up.

Key Performance Advantages

• Deep Color Rejuvenation: Restores dull, sun-bleached plastics to an OEM factory semi-matte finish without an artificial, cheap greasy shine.
• Long-Term Polymer Protection: Special bonding components resist multiple car washes and road salt wash-off.
• Winter Seal Protection: Penetrates rubber door and boot seals to keep them elastic and prevent door freeze-up during severe winter frosts.
• Anti-Static Barrier: Dries tack-free to significantly reduce road dust adhesion.

Recommended Application Protocol

• Preparation: Thoroughly clean plastic or rubber surfaces with Koch-Chemie Green Star or Allround Surface Cleaner and dry completely.
• Application: Apply a small amount onto a soft foam applicator (such as Koch-Chemie Applikatorschwamm) or microfiber sponge.
• Distribution: Work evenly and thinly into the grain of the plastic or tire sidewall.
• Leveling: Allow 5–10 minutes for absorption, then wipe away any excess with a clean microfiber cloth.

Precautions & Pro Tips

• Interior Restrictions: Do not use in vehicle interiors, on pedals, steering wheels, or tire treads due to slip hazards.
• Bodyshop Note: Contains high-grade silicone oils. For silicone-sensitive refinish shops, use Plast Star silikonfrei (PSS).
• Storage: Store tightly sealed in a cool, ventilated area (+5 °C to +25 °C).
