Thread Locker Use
We have provided a small tube of thread locker in
your kit. Whenever you see the symbol above on a step
of the instructions apply 1 small drop of the thread locker
to the threads of the screws or bolts. This will keep your
hardware from vibrating loose during rough driving. If the
hardware ever needs to be removed, do so slowly to
avoid having the inserts strip out from the plastic. DO
NOT USE ON LID HARDWARE, MAY CAUSE CRACKS.
