If you EDC -40, give the cotton balls a hit just before use, and add sparks while they are still juicy. Watch your eyebrows.

Me, I always have Carmex. White PJ base, with menthol and soothing stuff in it. Or Neosporin, which is white PJ with low order antibiotics. I carry the cotton balls dry, add a dab when needed, and fire it up. Even if the cotton gets a little bit of rain, the PJ burns enough on it's own.
