VHT SP995 550° Engine Enamel High Heat Spray Paint –

VHT SP995 Nu-Cast Aluminum is a high-heat engine enamel spray that bonds urethane and ceramic resins to create a durable, heat-resistant metallic finish for engine parts up to 550°F.

Engine bays and hot-running components demand coatings that resist heat, chemicals and road corrosion. VHT SP995 is formulated specifically for automotive engines and accessories, delivering long-lasting metallic coverage that dries quickly and gains full performance after proper curing. The 11 oz. aerosol is sized for touch-ups or full component refinishing, and the Nu-Cast Aluminum tone gives a factory-metallic appearance while standing up to modern fuels, degreasers and salt spray.

How does this paint hold up to high temperatures and engine fluids?

VHT SP995 combines urethane and ceramic resins engineered to tolerate sustained heat up to 550°F. It resists chemical attack from gasoline additives, common degreasers and road salts, helping coatings stay intact under harsh service conditions.

• Heat-rated to 550°F continuous service for engine components.
• Ceramic-enhanced formulation increases thermal stability.
• Resistant to gasoline, oil splashes and standard engine cleaners.
• Protects against rust and corrosion in exposed areas.

What parts and projects are best suited for this Nu-Cast Aluminum aerosol?

This spray is geared toward metal engine parts and accessories where both appearance and durability matter. Ideal targets include headers, valve covers, starters and housings that need a metallic finish that withstands heat cycles.

• Headers, exhaust components and manifolds.
• Valve covers, engine blocks and brackets.
• Transmissions, differential covers and other driveline housings.
• Restoration touch-ups and cosmetic engine bay upgrades.

What is the application process and how long until it reaches full strength?

Surface preparation and correct curing are essential for optimal performance. VHT SP995 dries to the touch in about one hour and is tack-free overnight, but the coating only achieves full heat and chemical resistance after being cured at operating temperature or by baking parts at around 200°F.

• Clean and degrease surfaces thoroughly before spraying.
• Apply light, even coats; allow flash time between passes.
• Dry to touch in ~1 hour; handle carefully after overnight cure.
• Final curing occurs with normal engine heat or by heating to 200°F.

How does this product fit into a complete VHT coating system?

VHT SP995 is part of a multi-step engine coating approach that includes primers, color coats and clear topcoats. Using the full system improves adhesion, longevity and the finished appearance compared with a single-layer application.

• Start with an appropriate VHT engine primer for best adhesion.
• Apply SP995 Nu-Cast Aluminum as the color coat for metallic finish.
• Seal with a VHT engine clear for added gloss and chemical resistance.
• Follow manufacturer instructions printed on the can for layering and cure.

Who is this for: VHT SP995 Nu-Cast Aluminum is aimed at automotive enthusiasts, restoration professionals and DIY mechanics who need a realistic metallic finish that resists heat and chemicals. It’s well suited for anyone refinishing hot engine components, repairing factory metal finishes, or adding a durable metallic look to performance parts that experience elevated temperatures.
