Nearly impossible to get. I wanted it for some wood protection on our outdoor train layout...but could not find it available anywhere.
Next best option is a product called
Termin 8 by Jasco (apparently now called Homax Products)
Typically it's found in green. But you'll want the harder to find Termin 8 "Black". A good creosote substitute, and a whole heck of a lot easier to find then creosote. I wasted almost three years trying to find creosote to buy...you just can't get the stuff anymore.
