After being out of fish work for several years, I took it up again to mount one for a friend. I have found that my Epo-Grip clear paste has really gone down hill. Part A has turned very hard and part B has dried up some, although digging down into it I did find some usable product. Question is: can this stuff be "revitalized" in some way or just time for some new? The jars are 3/4's full, just hate to discard if I don't have too.
