Hmm, I've done one mold a few years back to make a mag rapala about 25% bigger. I sure don't recall having any curing issues with the resin afterward, but I don't recall for sure which rubber I used. Might have been quick set. I do remember having issues with tearing if i wasn't really careful.
This looks like a question for Mike the Goop King. How large is the object you are making? have you tried heating the mold a bit?
