VHT Flameproof Coating, Gray, Flat ESP100000-1 Each

VHT FlameProof Coating (gray, flat) is a silicone-ceramic high-temperature primer and finish that protects exhausts, headers and other hot metal parts from extreme heat up to 2000°F.

Designed for applications where surfaces face intermittent or sustained extreme temperatures, this flat gray VHT coating delivers a matte finish and long-lasting protection. Originally developed for aerospace and automotive use, the formulation combines silicone and ceramic components to resist heat, oxidation and flaking on metal parts exposed to intense thermal cycles. Use it as a primer or as a topcoat on headers, exhaust systems and similar components where durability and appearance matter.

How does VHT FlameProof Coating stand up to high temperatures?

The coating is engineered to tolerate intermittent temperatures up to 2000°F (1093°C), using a silicone-ceramic base that maintains adhesion and finish under thermal stress. It resists bubbling, cracking and excessive color change when applied correctly and cured per instructions.

• Rated for intermittent exposure to 2000°F (1093°C).
• Silicone-ceramic chemistry minimizes oxidation and flaking.
• Formulation holds a matte flat appearance after curing.
• Works as primer or single-coat protective finish on hot metals.

What surfaces and parts can I coat with this product?

VHT FlameProof is intended for metal surfaces that experience very high heat. Typical uses include exhaust headers, mufflers, turbo housings and other components where standard paints fail from heat exposure.

• Exhaust systems, headers and manifolds.
• Turbocharger housings and heat shields.
• Custom fabrication parts on race and performance vehicles.
• Any ferrous or certain non-ferrous metals with proper surface prep.

How should I prepare, apply and cure the coating for best results?

Proper surface preparation and controlled application are crucial for adhesion and longevity. Clean, degrease and remove rust or scale, then apply in thin, even coats following manufacturer directions—finish curing typically requires staged heat cycling.

• Degrease and abrade metal, removing loose rust and contaminants.
• Apply thin, even coats; allow recommended flash times between coats.
• Cure by gradually exposing to heat per instructions for final hardness.
• Use in well-ventilated areas and follow safety guidelines on the label.

Will this coating change the look of my parts and how durable is the finish?

The flat gray finish provides a subdued, professional appearance that resists peeling and excessive discoloration under heat. While some color shift is normal with repeated extreme exposures, the coating is formulated for long-term protection and a consistent matte surface.

• Matte flat gray look ideal for understated or race-inspired aesthetics.
• Formulation minimizes peeling and flaking after heat cycles.
• Some patina or color change may occur after repeated extreme heating.
• Compatible as a primer under other high-temp topcoats when needed.

Who is this for: VHT FlameProof Coating is aimed at automotive enthusiasts, professional mechanics, fabricators and aerospace technicians who need a reliable, high-heat protective coating. If you work on performance engines, race vehicles, custom exhausts, or any application where metal sees very high intermittent temperatures, this product offers a robust balance of heat resistance, adhesion and a flat gray finish built for demanding conditions.
