INSTA-CURE+ Gap-Filling Super Glue 1/2-oz Bob Smith Ind

Bob Smith Industries INSTA-CURE+ is a medium-viscosity gap-filling CA (cyanoacrylate) glue built for the tougher joints in model railroading, RC building, and scale modeling. Where super-thin INSTA-CURE wicks into hairline seams, INSTA-CURE+ fills gaps up to 0.010" — perfect for parts that don't sit flush or for bonding rough, porous surfaces.

Best for: Gluing ballast, scenery ground cover, and rock castings in model railroad layouts. Bonds wood, metal, ceramics, and most plastics. Ideal when you need a few extra seconds of working time before the bond sets.

• Medium-viscosity gap-filling formula — stays in place, doesn't run
• 5–15 second cure on most surfaces
• 1/2 oz bottle with precision tip for controlled application
• Pairs with BSI INSTA-SET accelerator for near-instant curing
• Use BSI UN-CURE debonder to break bonds and reposition parts

For foam-safe gap-filling, choose BSI SUPER-GOLD+. For hairline seams and capillary wicking, use BSI INSTA-CURE thin formula.
