5 lb of Magic Sculp (sometimes called Magic Sculpt) by Wesco Two-part Epoxy Putty Sculpting and Modeling Compound. Manufacturer Info: Welcome to Magic Sculp - the two-part epoxy putty specifically designed to meet the needs of modelers, crafters and sculptors alike. One of the few epoxies that will smooth out with water. Its grain structure is finer than any other product available and will not shrink or crack even when formed in large structures. It can be shaped by hand or with modeling tools, sanded, carved, painted; you can attack it with a grinding tool and the cured material will not break apart or lose its shape. Magic Sculp will cure at room temperature. Features: - Magic Sculp will adhere tenaciously to most any surface, and can be sanded and painted when hard. - Easily mixed (Resin and Hardener slightly color coded: mix until one solid color). - Good adhesion to almost all clean surfaces, including glass. - Excellent malleability. - Good sculpting media: as easy to work with as oil clay. - Surface may be smoothed out with water. - Water and soap clean up. - Completely inert when cured. - Accepts all types of paint. - Surface may be sanded or ground when cured. - No measurable shrinkage. - Good for repairing anchoring bases and armature rods. - Indefinite shelf life. - Very forgiving on mixing ratio. Ratio may be varied to slow or speed up time. - Repairs low pressure leaking pipes of plastic, cast iron, stainless steel, and copper. Morezmore Experience: Not only Magic Sculp is great for building armatures and bases because of its superiour strength but it has fine enough grain to actually sculpt from it - see the 2" tall Firefly sculpture on the picture below. To use Magic Sculp, you simply mix equal parts of the resin and hardener, then knead together until a uniform color is obtained. It can then be shaped, sculpted and smoothed with a wet finger or modeling tools. It will harden in 1 1/2 to 3 hours.
