VHT Engine Metallic Spray Paint - SP403 Titanium Silver Blue 11 oz, Heat & Chemical Resistant

If you need a professional-looking metallic finish on engine components that can tolerate the extreme environment under the hood, this VHT Engine Metallic aerosol blends urethane and ceramic resins to give long-lasting adhesion and visual sparkle. It’s engineered for parts that are exposed to intermittent high temperatures and common garage chemicals, and it’s part of a complete VHT engine coating system when paired with primer and clearcoat.

How heat-resistant is this paint for engine parts?

The formula withstands intermittent temperatures up to about 650°F (343°C) once properly cured. Curing normally occurs in service as the engine reaches operating temperature, or you can accelerate full film properties by baking parts at lower controlled heat before installation.

• Rated intermittent resistance: up to 650°F (343°C)
• Develops full durability after correct heat curing
• Optional oven or controlled heat cure at ~200°F speeds development

Which engine components are best suited for this VHT metallic spray?

Use this aerosol on metal engine accessories and housings where a decorative metallic finish plus chemical and heat durability are required. It’s suitable for both restoration and performance applications on a wide variety of parts.

• Ideal: valve covers, headers, engine blocks, starters
• Also great: brackets, water pumps, transmissions, differential covers
• Works with primer and clearcoat from the same product family for top results

What surface prep and drying times should I expect?

Good adhesion starts with clean, dry, and properly prepped metal. The can includes complete application and curing instructions; typical handling times are fast, with full hardness achieved overnight or after heat curing.

• Touch dry in about 30 minutes under recommended conditions
• Thoroughly dry/fully set overnight or after heat cure
• Remove grease, rust, and old coatings; use recommended engine primer for best results

How does this product fit into a full engine coating workflow?

VHT Engine Metallic is designed to be one element of a high-performance coating system. Use VHT engine primer first on bare or repaired metal, apply the metallic color coat, and finish with VHT engine clear when a higher gloss and additional protection are desired.

• System: primer → color (this metallic) → clear for maximum protection
• Available in many OEM and universal colors for matching and customization
• Aerosol format offers easy application for hobbyists and pros
