Is this burn gel really that good, and does it have any other uses besides burns?  I just wonder if it's something that I would want to carry around every single day, as opposed to just having it in a regular (i.e. car or home) first aid kit.  I had never really thought something like that being absolutely essential that I would need it on me at all times, it seems like more of a luxury, but is it something that I should include in a kit? 
And instead of a dusk mask, I prefer to carry a bandana.  Specifically a red cotton boy scout bandana that I've been using for the past 20 years.  It seems to be the perfect size, iIt can be used as a reasonably effective dust mask, but has a variety of other uses too.
