VHT SP109 Flameproof Coating Very High Heat Spray Paint –

VHT SP109 FlameProof is a silicone-ceramic, matte red aerosol coating formulated to protect surfaces exposed to extreme temperatures up to 2000°F when applied and cured correctly.

This aerosolized high-temperature coating is engineered for components that run hot—like headers, mufflers and other exhaust parts—offering a durable, flat-red finish that resists heat degradation. Developed from materials used in automotive and aerospace applications, it combines ceramic and silicone chemistry to create a heat-tolerant film that both renews appearance and helps extend service life under intermittent ultra-high temperatures.

How does VHT SP109 protect metal under extreme heat?

The formula forms a heat-resistant ceramic-silicone layer that adheres to properly prepared metal, slowing surface breakdown and reducing oxidation. It’s designed for intermittent exposure to very high temperatures rather than constant immersion, so correct curing and layering are important for best performance.

• Silicone-ceramic composition resists heat damage
• Creates a matte, insulating film to limit surface oxidation
• Works best on clean, primed metal for optimal adhesion

Can I use this spray paint on my exhaust, headers, or engine parts?

Yes — this product is commonly used on exhaust systems, headers and other engine-adjacent components that experience high intermittent temperatures. For long-term durability, follow surface prep, primer, paint and clearcoat recommendations and allow full cure before exposing to extreme heat cycles.

• Suitable for headers, mufflers, manifolds and similar parts
• Recommended with proper primer and optional clear coat for best longevity
• Cure fully before repeated high-temperature use to reach rated heat resistance

What is the right way to apply and cure this high-heat coating?

Preparation is key: remove grease, rust and loose paint, then apply a compatible primer if needed. Spray in multiple thin, even coats, allowing flash times between passes; follow the manufacturer’s cure schedule—often involving a staged heat-up—to develop the final heat-resistant properties.

• Clean and de-grease surfaces thoroughly before spraying
• Apply several light coats rather than one heavy coat to avoid runs
• Follow the recommended heat-cure steps to achieve full temperature rating

What finish and color can I expect from this VHT aerosol?

The SP109 delivers a flat (matte) red finish that conceals blemishes while minimizing glare. Because it’s designed for performance rather than showroom gloss, expect a subdued appearance that blends with other race-inspired or under-hood components.

• Flat red matte finish for a low-gloss, factory-style look
• Good coverage with proper surface prep and multiple coats
• Pair with primer and clear coat if a different sheen or extra protection is desired

Who is this for: VHT SP109 FlameProof is aimed at automotive enthusiasts, fabricators and race teams who need a durable high-temperature coating for exhaust components, engine-adjacent parts, and other metal surfaces exposed to intermittent extreme heat. It’s best for users comfortable with surface preparation, spray technique and following curing instructions to achieve the product’s rated performance.
