Re: OK --- Now that I have it on my hands.... How to get it off? Remove Foam Sealant from Skin
(from Mr Fixit's link:)
Wipe moist foam with a cloth saturated in acetone nail polish remover.
Rub petroleum jelly on the foam dried to hands or fingers.
Place your hands in a plastic glove and wear for one hour.
Rinse the petroleum jelly and foam off your hands with warm, soapy water.
