Overview
Built for the job.
Trim Paints are acrylic coatings formulated to match the OEM finish on automotive trim components. For use on plastic, steel, aluminum, stainless steel and chrome.
SEM Trim Black 39143 is a 20‑oz aerosol trim paint formulated for precise color matching on exterior trim pieces. It delivers a durable, jet‑black finish on a variety of substrates commonly encountered in collision repair, including ABS, aluminum, OEM plastic, primer, and steel.
The aerosol provides professional results with a recommended application of four coats to achieve full opacity. With a VOC content of 682 g/L, the formulation is designed for consistent flow and flash time suitable for shop environments. The product’s compatibility with both metal and plastic surfaces eliminates the need for multiple specialty paints, streamlining the finishing process.
Due to its classification as acute toxicity, carcinogenic, and flammable, proper PPE is mandatory: eye protection, gloves, protective clothing, and a respirator must be worn. Use in a well‑ventilated area and store the can in a cool, dry place away from ignition sources.
