I used a product called Loctite which is essentially the same as D6. It's a
paste that, when applied to the threads of a screw or bolt, will prevent the
said bolt/screw from working it's way out due to vibration.
Loctite and similar products are available at any hardware/auto store. Make sure
you get the kind that will allow the bolt to be removed should you ever need to
do so in the future.
