It can't be normal spray paint, will melt the Styrofoam. Needs to be water based, kind of hard to find. Better if just paint with acrylic water based paint. Much safer and cheaper.
It's not the spray paint but the propellant that melts the plastic. Hydrocarbons, fluorocarbons mix into the paint and melt the foam. Even water based spray paint has propellant in it.
