Great tapping fluid

I remember Tap Magic from 35 years ago when I was working my way through college. Since then my life moved away from machining and the like. However, I've been getting back into metal working as a hobby. Cutting fluid is important for keeping your tools sharp, I'm using it on my band saw blades and it works well. If I were to be reborn as a cutting fluid, I would want to be Tap Magic. I'm not sure who would rate the scent though, it's not like I'm going to use it as cologne. But I rated it anyway, it brings back memories of being a poor college student and living off of a single pizza for three days. Back when you had dreams of your bright future, so I guess that makes it a nice scent.

I guess it works ok for what it's supposed to do, I haven't busted any more taps than usual anyway. But if it smokes, it STINKS like cat urine. Not the fresh stuff either, like the cat that peed on the carpet in the corner of the spare room and you didn't find it for a month kind of stink. And it sticks with you for the rest of the day too, the smell clings to your clothes for ages. That much I could forgive, I stink pretty good all on my own sometimes anyway. But the deal breaker for me is that it leaves this awful corrosive residue on everything it touches. I thought my new Kurt mill vise had begun to rust, but it was just this nasty stuff gluing it up. It took brake cleaner and a good amount of elbow grease to get it off. The final straw was when it gummed up my favorite little Goldenrod oil can so bad I had to throw it out. I don't know what I'll do with the rest of this junk now, I don't dare tip it into the waste oil burner, it'll stink out the whole neighborhood! It also gels up into a solid if it gets cold, in case you were wondering. So yeah, stay away from this stuff. Unless you want 3/4 of a gallon for free, then come see me!
