Quikwood epoxy putty stick comes in a plastic roll and stays soft until the two parts are mixed.
Hand-kneadable, fast-setting polymer compound. Just cut off a piece the size you think you may need. I don't like to get too much at once. You can always add more later if you need to. Using damp fingers Work the two sections together until they are one color. Attach your pieces and let cure. I enjoy the fact that the pieces stay together right from the get go. It Will not shrink or pull away. One hour after application it can be drilled, sawed, sanded, filed, and painted.
You can also sculpt or carve the product for intricate detail. It bonds to metal, glass, masonry and many plastics so you can attach many things to your gourds.
I am not selling this product anymore. I have heard they are going to quit making it but I think there are some suppliers that still have product. Smuckers Gourd Farm has it. Blue Whale Arts is still advertising it
