Best High Temperature Spray Paint
The PJ1 hi-temp spray paint makes the best heat-resistant paint for the exhaust systems. The spray paint can intermittent the heat around 1500°F which is quite good for headers. The paint won’t be peeled or cracked under this high extreme humid environment. And PJ1 Fast black color can retain the temperature of about 816 degrees celsius with higher durability.
Silica-Ceramic Hybrid
The PJ1 is the combination of two different properties formulated to make one. Silica helps in making perfect bonding with bare metal surfaces for a longer period of time. On the other hand, Ceramic-based are best suited in coating headers and giving a flat black matte finish look each time without being ripped off. When the metal heats it expands and as its cooldown, it’s contacted.
Resistant
The spray paint provides complete chipping and scratching resistance formula. It means its anti-rust formula as well. The PJ1 Flat Black Exhaust Paint offers protection against forming rust and corrosion on the surface. The special resistant properties make it the best paint for the exhaust headers in the automotive industry.
