TotalBoat TotalBond CA Glue Activator Spray for Super Glue - 2 oz Bottle

2 oz pump spray bottle of TotalBoat TotalBond CA glue activator. Sets thin, medium or thick CA on contact, which helps when holding a small model part in place until the glue grabs is not practical.

Our score7.8/10

CA glue is fast, but sometimes fast is not fast enough. When you are holding a photo-etch part with tweezers at an awkward angle, even a ten-second cure feels endless, and gap-filling CA can take minutes to harden fully. Accelerator, or kicker, cures cyanoacrylate on contact: mist or brush it on and the joint sets instantly, ready for sanding. That speed comes with trade-offs. Aggressive kickers can cause foaming, weaken joints, bloom near clear parts, or attack some paints, and delivery matters as much as chemistry since a broad spray wastes product where a brush pinpoints it. This guide compares hobby-safe accelerators by cure behavior, applicator type, and odor, so you can work faster without wrecking the finish.
