Replaces almost any cut gasket by making reliable "formed-in-place" gaskets that resist cracking, shrinking and migrating caused by thermal cycling. Coats pre-cut gaskets to increase reliability. Temperature range -65AdegF to 650AdegF (-54AdegC to 343AdegC) intermittent; resists auto and shop fluids. Applications:Automobile - Suggested Applications: Valve covers, oil pans, timing covers, thermostat housingsDirections:Surfaces should be clean & dry. Apply a continuous, uniform 1/16" to 1/4" bead of silicone, surrounding all bolt holes. 1/8" is suitable for most applications. Bead size may be varied by finger pressure, how quickly applicator is moved and angle. For heavier beads, nozzle may be cut to size.
