What is the shelf life of TG when it has been opened? What's up with the "4 to 8 tires" claim on the 250ml cycle bottle when your calculator shows 200ml for a standard pair of motorcycle tires? 4-8 (Bi)cycle tires seems to calc OK.
Cool product. Looks like the liter size is the way to go if it lasts on the shelf. My order is on the way.
