Overview

Built for the job.

2-in-1 trim black is a tough, flexible polymer coating designed to restore bumpers and flexible or rigid trim to their OEM condition. Transtar offers 3 gloss levels, matte, satin and gloss, to match the appearance on most vehicles. It has excellent adhesion to urethane, rubber, metal and treated olefin plastics. It isโ€ฆ

TRANSTARยฎ 4654 is a 1-qt aerosol can of 2-in-1 trim coating formulated for quick, high-quality finishes on automotive body panels. The satin black formulation cures to touch in 5-10 minutes, making it ideal for low-volume repair work and color matching where rapid turnaround is required.

Designed for a broad range of substrates-including aluminum, e-coat, fiberglass, galvanized steel, OEM plastic, primer, SMC, and standard steel-the product sprays directly from the can with no mixing needed. With a VOC content of 2.86 lb/gal (342 g/L) and a one-year shelf life, it provides consistent coverage while meeting environmental regulations for low-emission applications.

Because the formulation is classified as a Warning hazard, appropriate PPE-eye protection, chemical-resistant gloves, protective clothing, and a respirator-is required. Use in a well-ventilated area and follow all H-statements (H225, H304, H315, H319, H336, H351, H360, H373) for safe handling.

How to Use

For use on metal or plastic surfaces

  1. Clean the substrate (aluminum, e-coat, fiberglass, galvanized, OEM, plastic, primer, SMC, steel) to remove oil, grease, and loose material; ensure a dry, contaminant-free surface.
  2. No mixing required - product is supplied in an aerosol can ready for spray application.
  3. Apply the first coat with a consistent fan pattern. Allow 5-10 minutes for flash before applying additional coats.
  4. If a second coat is needed for coverage, re-spray after the initial 5-10 minute flash time; no additional pot life considerations apply.
