    I am making homemade disc for Disc Golf and this stuff is PERECT. Once set, the consistency was amazing. Can't rip it for the life of me. So strong.... highly recommend !

    Excellent rubber epoxy. Dense, flexible, transparent and easy to remove from molds. Sets very fast, 4 minute work time.
