Invisible Gloves
I've used a similar product from ACS; see:

Works great to protect against Proseal and MEK.
Also works well as a barrier cream while working with epoxy.
I recommend using it as a secondary layer (under latex gloves). Give it a minute or two to dry or it's pretty slimy stuff under the gloves. If you rip a glove, no worries.
