Bore-Wrap resin hardens as it cures.  It is a single component resin that activates with water so no mixing is involved.  The fiberglass architecture does not “cure” as fiberglass is already in it’s final state.  To check the cure, use a Calibrated Shore-D gauge on the highest point of resin to make sure the resin is cured.  Sufficient cure is at a Shore-D of 65 or greater.
