Bob Smith Industries SUPER-FIX Filler / Welding Powder is a fine additive designed to be used with cyanoacrylate (CA) adhesives to create a strong, gap-filling bonding compound. When combined with CA glue, the powder thickens the adhesive into a controllable paste that fills gaps, reinforces joints, and builds up missing material. SUPER-FIX Filler is ideal for seam filling, structural reinforcement, and repairing gaps where parts do not fit perfectly. Once cured, the CA and filler mixture forms a hard, durable bond that can be sanded, shaped, drilled, or filed, making it especially useful for scale modeling and precision repair work. A must-have companion to CA adhesives, this filler allows modelers and hobbyists to turn standard super glue into a versatile gap-filling and welding solution.
