Plastic-Cure - Plastic Model Glue
Plastic-Cure™ is a gap-filling formulation of CA that works best on plastics. It is packaged in a bottle with a brush built into its top, which in many cases is an easier way to apply the CA. As long as brush is put back into the bottle after use, the bristles of the brush will not harden.
Care must be taken, however, not to introduce foreign material into the bottle. The brush should not be used, for example, to apply CA to wood that has been freshly sanded.
Use include plastics, wood, foam, and false nails and wraps on fingernails.
