CA glue

CA glue, short for cyanoacrylate, is the super glue reached for whenever a joint involves something other than plain styrene plastic. Resin figures, white metal parts, photo-etched brass, and mixed-material joints like plastic to resin all rely on CA glue because it bonds by curing rather than by melting a shared plastic surface, which means it works across completely different materials in a single joint.

CA glue comes in different thicknesses similar to plastic cement, with thin formulas soaking into tight seams and thicker gel versions bridging small gaps or holding a part in position while it cures. An accelerator spray is often used alongside it to force a near-instant cure on a normal-setting glue, which is useful when a part needs to be held steady for only a second or two rather than a full minute.

A frequent mistake is using regular CA glue on clear parts like canopies, since the fumes it releases while curing can fog the plastic permanently, a problem specific enough that canopy-safe formulas exist for exactly this job. Another common issue is applying too much at once, which can cure white and hazy on the surface rather than staying invisible in the joint.
