What all is out there that can be lit with sparks from a large firesteel? I use the term "tinder" loosely - what I'm really after is "firemaking helpers that work with a spark"

I know of:

cotton balls with vasoline
char cloth
alcohol in a burner

What else is good and a reasonable thing to consider carrying on day hikes, etc.? Something that would work well in damp conditions and wind gets a bonus of course. "Fire Paste" would seem ideal IMHO, if it will take a spark. But I kind of doubt it will, and I don't have any to try experiementing with. Does anybody know if Fire Paste + spark = fire? I've got plenty of powder from ammunition reloading, but that fails under "wet" or "windy" conditions. Not to mention the safety aspect. Plus, you only get a flash of fire to singe your eyebrows with, not the more desireable slow burn to get other materials (tinder) ignited.

I am not concerned with weight and/or size that much. This would be for day hikes and bug out bag use.
