VHT Flameproof High-Temp Coating Spray for Exhaust & Engine Parts — Flat White 11 oz, Ceramic

If your headers, manifolds, turbo housings or exhaust valves need a durable finish that endures extreme heat, this 11 oz VHT formula provides a protective ceramic-silicone layer designed for automotive and industrial high-temperature applications. The flat white color offers a clean, low-sheen appearance while the aerosol EZ Touch nozzle makes application easier in tight or awkward spaces.

How does VHT Flameproof coating perform under extreme heat?

The coating uses ceramic-reinforced resins and silicone components to withstand intermittent temperatures up to 2000°F without blistering or rapid breakdown. It’s formulated specifically for parts exposed to combustion and exhaust heat rather than continuous furnace immersion.

• Rated for intermittent exposure to 2000°F (1093°C)
• Ceramic-silicone chemistry resists chipping and flaking
• Designed for direct-fire areas like exhaust and turbo housings

What surfaces and parts are appropriate for this spray?

Use this coating on metal components that see high thermal cycling: headers, manifolds, mufflers, turbine housings and exhaust valves. It adheres best to clean, degreased metal and is not intended for painted plastics or non-metallic substrates.

• Ideal for steel and cast iron exhaust parts
• Works on turbo housings and valvetrain components
• Not recommended for flexible or heat-sensitive plastics

How do I apply and cure VHT Flameproof for best results?

Shake the can thoroughly, spray thin, even coats using the EZ Touch nozzle, and allow touch-dry times between passes. The product feels dry to the touch in about 30 minutes and can be handled after roughly one hour, but following a proper heat-cure schedule improves durability and adhesion.

• Dry to touch in about 30 minutes; handle in about 1 hour
• Apply multiple light coats rather than one heavy coat
• Complete curing requires controlled heat cycles for maximum life

Will this coating change the look of my parts and how long will it last?

The flat white finish gives a subdued, low-gloss appearance that can refresh oxidized or discolored components. Longevity depends on operating temperatures, exposure frequency, and proper surface prep and curing; when applied and cured correctly it significantly extends service life of high-heat parts.

• Flat white provides a low-sheen, uniform finish
• Proper surface prep and curing increase lifespan
• Performance tied to operating conditions and maintenance

Who is this for: Technicians, DIY mechanics, performance tuners and fabricators working on engines, exhaust systems, turbochargers and other components that face intermittent extreme heat will benefit most from VHT Flameproof Coating. Choose this 11 oz flat white aerosol when you need a ceramic-silicone protective finish applied with an easy-spray nozzle and cured for long-lasting heat resistance.
