The TSA allows nail polish and nail polish remover up to the 3 oz limit for carry-on and no limit for checked baggage..
The TSA bans flammable paints and paint thinners. None allowed in carry-on and none allowed in checked baggage.
I looked up the MSDS's for nail polish, nail polish remover and paint thinner. Nail polish and remover have extreme or high flammability hazard while paint thinner has moderate hazard.
Somthing is wrong. And it isn't just the smell. Isn't nail polish a flammable paint?
