SEM Trim Black Aerosol Spray 15 oz — Acrylic OEM-style Black Finish for Plastic & Metal Trim

SEM 39143 Trim Black Aerosol is a 15‑oz acrylic trim coating designed to restore and match OEM black trim finishes on plastic, metal and chrome surfaces.

SEM's Trim Black aerosol delivers a factory‑style black finish in a convenient spray can for fast refreshes and repair work. Formulated to bond to a wide range of substrates—including plastic, steel, aluminum, stainless steel and chrome—this 15 oz can is intended for spot repairs, full trim refurbishing and detailing where an OEM look matters. It offers easy application, predictable coverage, and dries to a durable, uniform finish when proper surface preparation and technique are used.

What surfaces will SEM 39143 bond to reliably?

SEM engineered this acrylic trim paint to adhere to both metal and common automotive plastics, making it suitable for bumpers, mirror housings, side trim, and chrome accents. For best results, clean and degloss the surface before spraying to promote adhesion and a uniform appearance.

• Plastics: ABS, polypropylene after proper priming or adhesion promotion
• Metals: steel, aluminum and stainless steel with clean, rust‑free prep
• Chrome & plated parts: scuff, clean and apply a suitable primer when needed
• Interior trim panels: test compatibility first on hidden area

How should I prepare and apply the 15 oz SEM trim aerosol?

Surface prep is the key to a long‑lasting finish. Remove contaminants, sand or scuff gloss areas lightly, and use an appropriate primer or adhesion promoter where necessary. Shake the can well, keep it 8–12 inches from the part, and apply several light, even passes to avoid runs.

• Degrease with an automotive cleaner or isopropyl alcohol
• Scuff glossy or smooth surfaces with fine sandpaper (400–600 grit)
• Apply 2–4 light coats, allowing flash time between passes
• Allow full cure per product instructions before handling

What finish, durability and coverage can I expect from this trim paint?

SEM 39143 delivers a consistent, OEM‑style black finish that resists fading and provides a uniform appearance across varying trim parts. While aerosol coverage depends on technique and surface shape, its formulation is designed for professional and DIY touchups with predictable build and color match.

• Finish: factory‑style black with medium sheen suitable for trim
• Durability: formulated for automotive exterior conditions with good adhesion
• Can coverage: typical 15 oz aerosol yields multiple small repairs or a single larger trim set
• Color match: made to match common OEM black trim tones

How do I troubleshoot common application issues like runs or adhesion failures?

Runs often result from applying too much paint in one pass or spraying too closely. Thin, even coats and correct distance eliminate most running, while adhesion problems usually trace back to inadequate cleaning or missing adhesion primer on inert plastics and chrome.

• Runs: sand and feather the area, then reapply light coats
• Orange peel: allow flash time and apply additional light coats
• Peeling/poor adhesion: re‑prep and use recommended primer or adhesion promoter
• Color inconsistency: blend edges by feathering adjacent panels
