Aside from the intended use of fixing squeaky and rusty items, it's also a pretty damn good insecticide. I use it like Raid on wasps and other flying insects, with or without flame added.

Although, I must admit that it's a hell of a lot of fun to hold a lighter in front of the can and crisp bugs with it, especially wasp nests. Addictive even...the soft whoosh, the yellow tongue of flame...oh yes.

I'll stop now.
