While acetone is not considered highly toxic, I suspect that the irritant effects on skin vary with an individuals skin type, e.g., naturally oily vs. dry. The best policy is to use latex gloves when using epoxy, polyurethane and similar chemical products so that clean up can be done with IPA or soap and water, limiting acetone, MEK or other nasty toxic chemical direct skin contact for occasional minor clean-up mistakes. Why push the envelope unnecessarily? My step father was a house painter for most of his working career. Oil-based house paint is generally much less toxic than the lacquer, epoxy and polyurethane materials used on airplanes and automobiles. Nevertheless, after many years of daily contact with house paint and related solvents (including brush and roller cleaning and washing his hands with solvent), one day he put a turpentine-soaked rag in his back pocket for ready access, as was his long-time habit, and his backside turned red and got swollen. After that, his hands, face and chest would turn bright red any time he touched solvent or even got near an open can of paint. His body had accumulated too much of the chemicals, and was reacting to any more however slight. He then had to become an inspector, and stay away from paint! Words to the wise!
