SEM Trim Black Aerosol Spray 15 oz — OEM-Style Acrylic Finish for Automotive Trim

SEM 39143 Trim Black Aerosol (15 oz.) is an acrylic spray designed to restore or refresh automotive trim with an OEM-style black finish on plastic, steel, aluminum, stainless steel and chrome.

When you need a fast, consistent black finish for exterior trim pieces, door handles, mirror housings, grilles and other small components, the SEM 39143 trim aerosol delivers a durable, factory-appearance coating in an easy-to-use aerosol can. Formulated as an acrylic coating, it’s intended to closely match original equipment manufacturer (OEM) trim tones and bond to a variety of substrates without requiring complex mixing or spray equipment.

What surfaces can I use this trim spray on?

The SEM 39143 is formulated for broad compatibility across common automotive materials, so you can use it on both painted and bare components. It bonds well to plastics (with appropriate preparation), bare and painted steel, aluminum panels, stainless finishes and even chrome after proper scuffing and priming.

• Plastics: bumper covers, mirror housings, cladding (prep with plastic adhesion promoter)
• Metals: steel and aluminum trim, brackets, small panels
• Stainless and chrome: scuff, clean and prime before coating
• Works on both OEM-finished and previously repainted parts

How does it achieve an OEM-style black appearance?

SEM uses acrylic resin and pigment formulation to replicate the depth and sheen of factory trim. The product lays down evenly from the aerosol for consistent color and texture, minimizing brush marks and providing uniform coverage across complex shapes.

• Acrylic chemistry for good gloss control and color hold
• Aerosol spray pattern engineered for even application
• Fast drying film that reduces runs and sagging on vertical surfaces
• Part number 39143 ensures the correct OEM-referenced shade

What preparation and application steps give the best results?

Surface cleanliness and light abrasion are the keys to long-lasting adhesion and a smooth finish. Follow standard prep: clean with an appropriate solvent, scuff glossy surfaces, and use primer or adhesion promoter on plastic and chrome areas when needed.

• Clean: remove grease, wax and contaminants before painting
• Scuff: sand glossy or chrome surfaces with fine-grit abrasive
• Prime: use a plastic primer or metal primer where adhesion is a concern
• Spray: apply multiple light coats from the recommended distance for even coverage

What package details and fit information should I expect?

The SEM 39143 is supplied in an individual 15-ounce aerosol can suitable for universal fit applications on most automotive trim parts. The can dimensions make it easy to store in a typical shop toolbox or parts cabinet.
