Sorry Chris, I'm not familiar with this product, but a mate who works at chainsaws and similar for a living swears by a Briggs and Stratton fuel stabiliser, that he also uses in his bikes.
Personally, all I ever do if I'm laying up a bike for a bit, is drain the tank, then suck the remainder out by using a tube on a vacuum pump, then leave petrol cap off for a bit, to allow anything left to evaporate. Also drain carbs. Sounds a lot of hassle, but only really takes a few minutes.
