It appears that the oil, benzene and 95 efficient foam is the best mix and efficiency in the use of glue from the glue from foam polystyrene is better done from each pattern is made thinner and kerosene.
It appears that the fuel efficiency of 95 benzene solvents and foam has the best efficiency in the use of glue foam has superior adhesive foam made from solvents, thinners and kerosene.
That oil benzene 95 efficient to do melt foam well and most efficient in the use of glue from the foam is better than the adhesive foam made from solvent thinner and kerosene.
