Plasti-Craft SuperPlastic Goop SuperPlastic is made to be a substitute for the old Topper SuperPlastic and also to replace the old Toymax Plasti-Steel. It is thicker than regular goop and pours like honey. It bakes just the same so it will cook in any Creepy Crawlers oven or regular oven that gets to 325-350 F. When the Superplastic is hot it is soft and can rip easily. After it has cooled it becomes a hard plastic. It is great for pieces that need to be rigid. It is completely mixable with Official Plasti-goop and regular Plasti-craft goop. Superplastic will be available again shortly.
