Super-Gold+ is a gap filling, medium viscosity foam-safe cyanoacrylate glue that is (nearly) odorless, and does not frost nearby surfaces as it cures. Curing time is 2 or 3 seconds longer than traditional CA glues of similar viscosity, but the slower cure time and different formulation prevent the sudden heating that can damage foam surfaces as CA glue cures. You can use Insta-Set CA Glue Acclerator in a very fine mist, but do not apply too much accelerator, or you may damage foam surfaces.
