Dupli-Color Metalcast Blue Anodized Coating - Durable High Heat Finish

In this review the Dupli-Color Metalcast Blue Anodized Coating is examined for automotive enthusiasts who want a transparent, colored finish over chrome or polished metal. The bottom line: it is best for DIYers seeking an easy one-step spray that creates a bright, metallic blue look and stands up to under-hood temperatures, with the single biggest reason to buy being its combination of anodized transparency and high heat resistance in a ready-to-use aerosol.

Key Features

• One-step anodized finish: Turns ordinary chrome and shiny metal pieces into a bright, transparent-colored metallic surface without complicated multi-part processes.
• High heat resistance: The enamel formula tolerates intermittent heat up to 500F, making it suitable for some under-hood components and other hot spots.
• Durable composition: The paint is formulated to resist oil and gasoline exposure, which helps maintain appearance in automotive environments.
• EZ Touch Fan Spray: The aerosol features a fan spray nozzle for wide, even coverage that makes application on curved chrome accessories simpler.
• Quick handling: Dry to the touch in about 30 minutes and able to be handled in approximately 1 hour for faster turnaround on small projects.

Who It's For

This spray is aimed at car and truck owners, restorers, and customizers who want to change the color appearance of chrome or polished metal parts like trim, emblems, and small accessories without replacing them. It is also useful for ATV, UTV, and motorcycle projects where a transparent anodized effect is desired.

Those who need a perfect color match for painted body panels or who plan to coat stainless steel without extensive surface preparation may want to look elsewhere; adhesion can vary depending on substrate and prep, so it is best used over properly prepared shiny, bare metal or faux chrome surfaces.

Pros & Cons

Pros

• Creates a bright, transparent metallic blue that enhances chrome pieces without hiding the underlying texture.
• Resists oil, gas, and intermittent heat to 500F, useful for some under-hood applications.

• Durable enamel formulation suitable for interior and exterior automotive use.

Cons

• Color and adhesion can be mixed depending on the exact substrate; some users report it may not stick to stainless steel without additional prep.
