Best for: Bonding vinyl, neoprene, rubber tires on RC cars and trucks, leather, and flexible tubing. Excellent for repairing foam or vinyl RC body panels, attaching rubber gaskets, and any joint that will flex in use. Also works on wood, metal, and rigid plastics where some give is desirable.

• Flexible formula — cured bond flexes instead of cracking under stress
• Super-thin viscosity wicks into tight joints
• 3/4 oz bottle with precision tip
• Ideal for RC body repair and rubber-to-substrate bonding
• Pairs with BSI INSTA-SET accelerator for faster cure

Say Goodbye to Fumes and Foam Damage with SUPER-GOLD+ Gap-Filling Odorless Foam Safe Super Glue

Many hobbyists and model builders face the challenge of adhesives that release strong, irritating fumes or harm delicate materials like white foam and clear plastic. This problem not only disrupts the workflow but also makes working on projects uncomfortable and poses potential health risks over time.

These issues often result in eye and nose irritation caused by smoky glue fumes, while adhesives that damage foam or fog clear plastic spoil carefully crafted projects. The consequence is wasted materials, increased stress, and diminished enjoyment in crafting or repairs.

Introducing SUPER-GOLD+ Gap-Filling Odorless Foam Safe CA Glue—the perfect solution for those looking to avoid these common problems without compromising on bonding strength or speed.

• Odorless INSTA-CURE formula that won’t irritate your nose or eyes
• Foam safe and non-frosting, ideal for foam core wings and plastic-foam assemblies
• Fast bonding with a slightly flexible cure that enhances shock absorption

This premium glue will not fog clear plastic, making it excellent for attaching delicate clear canopies in plastic model kits. While MAXI-CURE is ideal for general plastic assembly, SUPER-GOLD+ stands out when working with foam and clear materials.

Users report that wood bonds to white foam in under fifteen seconds without causing damage, and foam-to-foam joints can be further strengthened by applying a light fog of INSTA-SET with this glue. Many hobbyists praise its superior performance and comfortable application without the harsh fumes common to other cyanoacrylates.

Don’t let inferior adhesives slow your creativity or ruin your prized models. Choose SUPER-GOLD+ Gap-Filling Odorless Foam Safe super glue for a fast, safe, and effective bonding experience that safeguards both your materials and health.

Order now to enjoy hassle-free, odorless bonding with excellent gap-filling properties, perfect for all your foam and plastic crafting projects.
