A. Lay a continuous bead of epoxy into the bottom of the first shutdown rail slot from the finish line out to the end of the shutdown.  Lay three pieces of shutdown rail in the slot with the good end .032" away from the drag strip rail at the finish line.  This gap is important as no electrical current is desired in the shutdown.

B. Apply even pressure to the rails as they are worked into place along the shutdown from the finish line to the end of the shutdown.


Tapering the shutdown rail upward from the finish line to the end may increase the shutdown's overall effectiveness.

C. When within a few feet of the end of the shutdown, cut and trim the shutdown rails flush with the end of the shutdown.  Continue to work the remaining shutdown rails into place.

D. Complete the above process for the other three shutdown rail slots.  Change premixer and tip as the epoxy nears the end of its working time.  Use naptha or similar cleaner and a clean, lint free rag to remove any excess epoxy prior to curing.

E. Apply pressure over the entire shutdown while the epoxy cures to ensure that all shutdown rails are as even as possible.
