polystyrene (styrofoam) dissolves in acetone (common in nail polish remover) . the goop that is produced dries out to form something I affectionately call ghetto-resin, useful as a sealant and prolly other stuff too.

tell me about your findings with this material (new uses, approximate mix ratios, etc.) all contributions appreciated

Many solvents will work with it. Polystyrene isn't UV stable, but as an indoor varnish it's very shiny. In high strength solution it is a good adhesive for broken styrene and polystyrene items.
