calcium chloride for ag tire use must not be buffered typically, because it would eat tractor and implement rims pretty quick. If we didn't clean our tools afterward it would rust them in a day or two..pretty nasty stuff and rough on boots as well
It's used to pump calcium chloride into ag tires for weight it weighs more than water or antifreeze and doesn't freeze.. Only problem is it eats rims into Swiss cheese I'm surprised it isn't rusted out must not have been used a whole lot I'm a sucker for old Firestone stuff
