Hey Wing!
I hear you....I had a chemistry teach that would get pissed if you said "Styrofoam" or "Kleenex"....heaven help any kid that mixed up "transparent" and "colorless".
One of my first calls was to a company called Rot Doctor..they sell a product that is supposed to seal up wood and stop rot...I was telling him my issues and he said the following...
"High density foam is usually polyurethane-based, in which case CPES will have no effect on it. CPES is only incompatible with Styrofoam."
So I called Aerolight customer service to see if it was extruded polystyrene vs. high density foam....they confirmed that the floor is not extruded polystyrene...the walls are a different story as they do contain extruded polystyrene.
I'm not a chemist, so I don't I really get what all this means, but I ordered a bunch of Rot Doctor stuff hoping it will help get the job done (and not melt the foam at the same time).
T.
