Permatex Hi-Temp RTV Silicone Gasket is formulated for high temperatures and heavy duty use. Red RTV is designed to maintain maximum performance at continuous 600F temperature. RTV Gasket Maker moisture cures at room temperature. This vulcanizing gasketing compound resists aging, weathering and thermal cycling without hardening, shrinking or cracking. It endures temperatures ranging from -75F to 650F intermittent.
The red silicone really is a high temperature sealant. Other silicones do not work like this stuff. I have used it many times in hot locations on engines. Works well near exhaust manifolds, etc.
