Find nitrile gloves rather than latex ones ! The latex variety are not very resistant against whatever-the-nasty-stuff-is (as I have read repeatedly). The same Health and Safety source should have both, though perhaps not the local pharmacy.

BTW, your efforts have inspired me to try RA4 too, in case it disappears soon - only not at the moment when half the apartment appears to have ice on the inside. That's only a slight exaggeration too. I am looking for a local-ish supplier of the Kodak chemicals, as starting off with a sub-optimal version of the chemistry from another manufacturer is not the happiest idea.
