Cyanoacrylate
Not the super glue from the hardware store aisle.
Generic CA is built for generic jobs, not the plastics, composites, and other materials this hobby actually works with. That's why CowRC carries Bob Smith Industries' full CA lineup, spanning viscosities from water-thin to extra-thick gap-filling, along with specialty formulas for foam-safe builds, flexible bonds, and rubber-toughened strength, so there's a genuine match for whatever you're bonding, rather than one glue asked to do every job.
Beyond the glues themselves, this lineup includes the extender tips, applicators, and tubing that help apply them with real precision. None of it is strictly necessary to get a bond done, a bottle straight from the nozzle will still work, but once you're using CA regularly, these small accessories are what let you dial in exactly how much goes where, instead of fighting the bottle to get it right.
One tip from the team: match the viscosity to the joint, not just the material. A tight-fitting seam wants a thin CA that wicks in, while a loose or gapped joint needs something thicker to bridge it, the wrong thickness for the fit is often the real reason a bond doesn't hold.
