Do NOT apply on your exhaust flanges
My heart is still pounding as I was rushing in all directions trying to get something to extinguish the fire with. I applied this RTV on the collector flange, downstream the headers, to arrest a leak and correct the AFR reading on the wideband. I saw some smoke, and I thought maybe it's the high temp paint on the header. Next I saw flames, and you know the rest. Beware, for your own safety!

Este sellador de silicona de alta temperatura ha funcionado de manera excelente en las uniones del escape de mi motocicleta. Su resistencia al calor extremo garantiza un sellado duradero sin deteriorarse con el tiempo. La aplicación es sencilla y la adherencia es muy buena, asegurando que no haya fugas ni vibraciones molestas en las conexiones. Además, su formulación a base de cobre proporciona una excelente conductividad térmica y estabilidad en condiciones exigentes. En general, un producto confiable y altamente recomendable para sellar uniones expuestas a altas temperaturas, como sistemas de escape y componentes de motor. ¡Gran desempeño!
