Farnam's Furall aerosol wound treatment is not going to be available for about a year.  The plant where it was made burned to the ground.  Farnam estimates that it will be about a year before Furall is in production again.  In the meantime, for aerosol wound treatment we recommend Wound Kote aerosol with methyl violet or the Scarlex aerosol with scarlet oil.  If you can use a cream instead of an aerosol, the Nitrofurazone ointment has the same active ingredient as Furall.
