Leftover epoxy (Foster & California Ave)

Have any leftover epoxy+hardner that you can spare? Only need about 1/2 cup (will take more if offered though). Need to fill a large vertical hole in wood so I don't think the runny/liquidy kind will work (correct me if I'm wrong). I'm thinking more pastey kind (consistency of JBWeld, Bondo, etc). Will bring my own containers if needed.
