Best water putty

[River jigin 10]

I want to make some molds for some jig heads and was wondering what would be the best water putty to use or what ever is the best material for making molds, for jig heads? Thanks, Vince

If you don't need a metal mold try these.

A High Temp RTV i.e, Dow Corning 1320. It will last for years.

Next would be Bondo Body filler mixed with Bondo resin to the consistency of Honey.

That way you'll get no water explosions and it wont crumble.

Anything you mix with water needs to be fully dried and tend to break down rather quickly.
