Surfaces should be clean & dry. Activate PowerBead™ by twisting nozzle one full turn counterclockwise, raising trigger. Press trigger to dispense. 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. Assemble parts immediately. Finger tighten bolts until material begins to squeeze out around flange. Allow to dry for 1 hour then retighten 1/4 to 1/2 turn. Silicone will fully cure in 24 hours. After use, store applicator by twisting nozzle clockwise, wiping away excess silicone & replacing plastic cap with a “click”.
NOTE: Not recommended for use on head gaskets or parts in contact with gasoline.
