      Is it a "gel" or more like a potting compound ?

      I used Methyl Ethyl Keytone (MEK) to open potted circuits from 
competitors when i was in design and manufacturing engineering.

      Worked great and even left identification of parts intact.

      I don't suggest you specifically use MEK without further investigation.

      The stuff I was dissolving, which actually took hours depending on 
volume, was potting compound, (very similar to injection molding materials) not 
a gel.

      Worth an investigation anyway.

        hi all
        i am working on my snowmobile,i have to work on a special board that 
has a kind of GEL to protect the circuit from
        humidity...
        i remember some years ago in a radio-mobile shop they add a kind of 
liquid that you drop over this gel and it would melt it!!!!!!!!
        someone maybe know what i am talking about ,?
        i dont remember what it was.
        thanks for your help

        i need it to repair my board,,,,,,, ,,,,if i can
