SEM Trim Black Ultra Spray Paint 14.5 oz — Jet-Black Gloss for Plastic, Aluminum & Steel, OEM Match

SEM 49153 Trim Black Ultra is a 14.5 oz aerosol that delivers true jet-black, OEM-style gloss and fast coverage on plastic, aluminum, steel and stainless steel.

This professional-grade aerosol is formulated to give trim and exterior parts a deep, consistent black finish with smooth sprayability and high transfer efficiency. Designed to match original equipment manufacturer (OEM) appearances, the product offers three gloss levels to coordinate with different vehicle surfaces and trims. Its quick coverage and adhesion to substrates such as steel, aluminum, TPO and polypropylene reduce time and coats compared with conventional aerosol paints.

How does this spray perform on automotive trim and exterior parts?

SEM 49153 is engineered to lay down a uniform, jet-black film that mimics factory finishes. It sprays evenly with minimal runs when applied per instructions and bonds well to common auto substrates after proper surface prep.

• True jet-black pigment for factory-matching appearance
• Three gloss levels available to match surrounding trim
• High transfer efficiency reduces overspray and the number of coats
• Formulated for smooth flow and reduced orange peel

Which materials will it adhere to and what prep is needed?

The trim black formula adheres to steel, aluminum, stainless steel and many plastics such as TPO and polypropylene when the surface is prepared correctly. Proper cleaning, scuffing and, if required, a compatible primer will improve adhesion and longevity.

• Works on steel, aluminum and stainless steel substrates
• Suitable for TPO and polypropylene plastics with appropriate prep
• Recommend degreasing, sanding or scuffing before application
• Use SEM-approved adhesion promoters on difficult plastics

How do you get the best finish with this aerosol can?

Apply using steady, overlapping passes from the recommended distance to build thin, even coats. Allow flash time between coats and follow any recoat windows to avoid surface defects and get a smooth, OEM-like result.

• Shake can well before use and during painting for consistent flow
• Spray 8–12 inches from the surface in thin cross-coats
• Allow flash time between coats and follow manufacturer dry times
• Mask surrounding areas to prevent overspray and achieve clean edges

What gloss options are available and why choose them?

Three distinct gloss levels let you match existing factory trim or achieve the desired aesthetic. Select a gloss that complements adjacent panels to maintain a cohesive, original look.

• Low gloss for understated, matte-looking trim
• Medium gloss for a balanced, factory appearance
• High gloss for deep shine and polished trim sections

Who is this for? SEM 49153 Trim Black Ultra is aimed at professional detailers, body shops and experienced DIYers who need a reliable aerosol that reproduces OEM black finishes on automotive trim and exterior components. It’s suited for projects where appearance, adhesion and efficiency matter—restoring bumpers, mirror housings, moldings and metal trim pieces—provided recommended surface prep and safety practices are followed.
