{"product_id":"smooth-on-plasti-paste-support-shell","title":"Plasti-Paste Support Shell","description":"\u003cp\u003eRubber molds need support structures that won't slump mid-application or add unnecessary weight to your workspace. Plasti-Paste stays exactly where you spread it on vertical surfaces, building up reinforcing shells without the frustration of gravity-induced sagging. Fiber-filled formulation cures to a rigid yet lightweight plastic that provides genuine structural support for flexible molds without the heft of traditional mother mold materials.\u003c\/p\u003e\n\u003cp\u003eThis paste functions equally well as an industrial-strength adhesive for equipment repair and fabrication bonding. Once cured, the resulting surface accepts standard workshop finishing: you can sand it smooth, drill mounting holes, or machine it to precise tolerances. Add pigments to match existing structures or create visual coding for different mold sections. The combination of workability and final strength makes this material valuable beyond mold-making, sculptors use it for armature reinforcement, prop makers rely on it for structural repairs, and fabricators keep it on hand for bonding dissimilar materials.\u003c\/p\u003e\n\u003cp\u003eApply with palette knives or spatulas to build up thickness gradually. The paste won't run or drip during application, letting you focus on creating even coverage rather than fighting the material's tendency to migrate.\u003c\/p\u003e","brand":"Smooth-On","offers":[{"title":"pint","offer_id":47973725339877,"sku":"15213","price":55.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/6890\/5701\/files\/s15213.jpg?v=1761724871","url":"https:\/\/www.texasart.mom\/products\/smooth-on-plasti-paste-support-shell","provider":"Texas Art Supply","version":"1.0","type":"link"}
