I got a health question regarding using some chemicals on our cars

I stir my coffee with a pen or screwdriver at work. No ill effects on me. LOL but in all seriousness i wear rubber gloves at work and do use MEK . But i do wear a respirator when spraying , or grinding/sanding on parts. Like others have said chemicals can be toxic hence the warning labels , but most of the warnings have to do with over exposure to these things. Being smart and wearing appropriate PPE while working with chemicals, and washing your hands before handling food helps. But one exposure like what you were mentioning is prob not gonna hurt you.
