Problem I have with canola oil is that it goes bad fairly quick when you leave your pans hanging up. Bad as in the pans get all tacky and feel cruddy if you don't use them for a while. I've been using a Crisbee swipe (basically a rag saturated in crisbee "cast iron seasoning") which i apply after I wash/reheat. It's basically a beeswax blend with some other vegetable oil in it I can't really remember. The idea is that beeswax pretty much lasts forever. I've had good results with it but the rag is almost ready for the trash after the 9 or so months I've been using it. That Buzzywaxx stuff is similar to Crisbee, a beeswax blend which also has grapeseed oil in it.
