Dupli-Color DE1640 Engine Enamel Spray Paint with Ceramic – Plum Purple, 12 oz Aerosol Can

Overview

Dupli-Color DE1640 Engine Enamel with Ceramic is a high heat spray paint designed for under the hood surfaces of cars, trucks and more. Its ceramic resins help with heat dissipation and gloss retention while offering protection against typical automotive fluids that can contact engine components. The plum purple shade combines durability with a vibrant finish that stands up to regular service and environmental exposure.

Why this color and formula stand out

The Plum Purple color is formulated for long lasting visibility and a resilient surface on engine blocks and accessories that live in heat and vibration. The enamel is designed to stay visually appealing even after repeated heat cycling and maintenance. Its ceramic component adds a protective layer that helps maintain a smooth surface and a glossy appearance over time.

• Heat resistance up to 500°F intermittently, helping the finish endure typical under the hood conditions
• Gloss retention through ceramic resins for a lasting, showroom-like shine
• Protection from automotive fluids and common contaminants that contact engine surfaces
• EZ Touch Conical Nozzle for smooth, even coverage on engine blocks and irregular shapes

Application workflow you can follow with confidence

• Prep surfaces with Dupli-Color Prep Spray to clean and degrease the area
• Apply a compatible primer designed for engine surfaces and allow adequate drying
• Lay down two light coats, followed by one medium coat in the desired plum purple color
• Dry to the touch in about 30 minutes and handle with care after roughly an hour

Ideal uses and practical benefits

Designed for under the hood work on cars, trucks and off road vehicles such as ATVs and UTVs. It suits racing projects, street rod builds and restorations where a durable color and protective finish are valued. Results can vary by surface condition, prep quality and environmental factors, but the enamel is built to perform under common high heat and fluid exposure scenarios.

Dupli-Color has been a trusted name since 1938, offering a broad range of engine enamels along with primers and clear coats to help color match and protect your restoration or customization project.
