Query: Works great but is quite toxic

This stuff is amazing and completely useful if you superglue stuff more than occasionally. I've never seen it in a store, possibly because it is quite toxic. I have to be very careful not to breathe the fumes, or I get a day-long headache. I also know a co-worker who got some in his eye and suffered permanent damage to his vision. Also, it speeds up the superglue so much that the it gets extremely hot (sometimes even smokes).In a nutshell, this product works great but BE CAREFUL.
