    Isokote 531 has a spray on amazon that was used in a molding and casting video I watched recently. The video release a bondo/resin fish from a fiberglass mold. I have done this with wax and PVA in the past.

    I have a first pull fiberglass walleye that is a couple years old. The mold is now breaking down and I want to make a new one from the original cast.

    If I apply the isokote release can I bondo/resin mold the original casting?

    Suggestions with the process.
