Coghlans Fire Paste

This stuff has been around for ages and it's great.  Squeeze a little on some pieces of wood before you start your campfire, then light the paste.  Use it on charcoal the same way.  The paste will stay lit for a few minutes and by that time your fire should be established.  You can even rub a little on the generator of your gas stove and ignite it to warm up the stove for easier lighting.
