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. Activate PowerBead™ by twisting nozzle one full turn counterclockwise, raising trigger. Press trigger to dispense. Assemble parts immediately while silicone is still wet. Silicone will fully cure in 24 hours. After use, store applicator by twisting nozzle clockwise, wiping away excess silicone and replacing plastic cap with a “click”.
NOTE: Not recommended for use on head gaskets or parts in contact with gasoline.
