Here is something many (some?) may recall there once was a time when refrigerants we're widely available to the public no license required. In fact I purchased a 30lb contIner of Forane R-12 from Costco around 1994 which I still have minus about 8 lbs.
Which leads me to this question does anyone know the shelf-life for these products?
