TRANSTAR® 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

- No mixing required - product is supplied in an aerosol can ready for spray application.
- Apply the first coat with a consistent fan pattern. Allow 5-10 minutes for flash before applying additional coats.
