I've had ups and downs with this putty. I bought it thinking I could use it for small masters or molds, but it was the wrong consistency (too complex to work with easily) so I put it aside while trying to find a use for it Find. tried it for sealing molding boxes and similar work. It's also great for gluing parts together - it cures fairly well and isn't difficult to remove. Overall I like this stuff, although it's quite pricey for what you get.
