You aren't kidding there ... I was careful, wore gloves, etc ... and still got a light smear on my leg, probably came off of some newspaper I had put down. It was on there for about an hour when I discovered it. I had to attack it with a nail brush for a good 5 minutes to get it off. If it had been a thick spot of it, I am sure it would not of come off. dizzy and light-headed? ... nah ... don't remember any of that ... don't remember using the stuff, either ...
