Dupli-Color Metalcast Anodized Spray Copper, 11 oz — Translucent Heat‑Resistant Metallic Finish

Dupli-Color Metalcast Anodized Coating in Copper is a translucent, one-step spray that produces an anodized-look metallic finish over chrome and polished metals.

This aerosol formula was developed to deliver a bright, transparent colored metallic effect without the time and equipment of true anodizing. Applied over properly prepared chrome or highly polished metal, the copper shade tints the underlying shine and gives a heat-resistant, chemical-resistant decorative finish suitable for many interior and exterior projects. It bonds to bright metal surfaces and is designed for fast, single-coat results when used as directed.

How do I prepare chrome or polished metal for the Metalcast Anodized finish?

Surface prep is essential for an even, durable anodized look. Begin by cleaning away oils, wax, and dirt with a suitable degreaser; lightly scuff any contaminants but avoid dulling the chrome’s reflective quality. Use a tack cloth to remove dust and ensure the metal is completely dry before spraying.

• Clean with a grease-cutting solvent; rinse and dry thoroughly.
• Lightly abrade only if necessary—retain mirror-like areas for the translucent effect.
• Shake the can well and test-spray on a scrap piece first.

What performance can I expect—heat resistance, chemical exposure, and longevity?

Metalcast offers intermittent heat resistance up to 500°F and resists common automotive chemicals, making it suitable for decorative trim, engine bay accents, and exposed metal surfaces. While durable for decorative applications, it is not a structural coating and should be used where abrasion and heavy wear are limited. Periodic inspection and gentle upkeep will keep the finish looking its best.

• Intermittent heat tolerance up to 500°F for high-temperature accents.
• Resistant to many automotive fluids and light chemical exposure.
• Best for decorative areas rather than high-abrasion surfaces.

How do I apply the copper Metalcast spray for a consistent anodized appearance?

Apply multiple light passes rather than one heavy coat to avoid runs and pooling. Hold the can 6–8 inches from the surface and use steady, overlapping strokes; a thin transparent layer preserves the polished-metal reflection beneath. Allow proper flash time between passes and follow the can’s drying instructions before handling or reassembly.

• Maintain 6–8 inch spray distance and use steady, overlapping passes.
• Multiple thin coats build color while keeping metal reflection visible.
• Allow recommended dry/flash times between coats for best adhesion.

Can I use Metalcast Copper on exterior trim and interior details?

Yes—when applied to prepared bright metal, the copper Metalcast creates an attractive accent on both interior and exterior trim pieces. For exterior use, protect from harsh road debris and heavy abrasion; for interior applications, its translucent metallic tone adds visual depth to polished hardware and accessories.

• Great for trim, bezels, emblems, and decorative engine components.
• Interior use enhances polished hardware without hiding shine.
• Exterior use recommended where impact or abrasion is minimal.

Who is this for? Dupli-Color Metalcast Anodized Coating in Copper is aimed at automotive enthusiasts, custom fabricators, detailers, and DIY makers who want a quick, anodized-looking metallic tint on chrome and bright metal surfaces without specialized anodizing equipment. It suits projects where a translucent colored metal appearance—combined with heat and chemical resistance—is desired for visual impact rather than heavy-duty protection. Follow surface preparation, application, and safety instructions on the can for best results.
