I have sometimes experimented with using lip balm in this roll. Seems to work in warmer temperatures when you can kneed it into a cotton ball. I suppose if the wax got too cold to work you could simply cut a chunk off with a knife, roll it in a bit of cotton cloth cut from the always useful, but expendable, bandanna and light the corner.

I find that lib balm is pretty handy, and even more handy if you get the stuff with a significant sunblock rating. A touch smeared on the nose, ears and lips makes a big difference preventing sunburn. I have also used lip balm to prevent rust and lubricate simple mechanisms like a the old P-38 and jackknife. Seems to work pretty well.

The combination of lip balm, sunblock, fire starter, lubricant and rust blocker covers a lot of ground in a small package.
