Just a thought on sandpaper, but in a big area like you are in there may be a machine shop or a wood working shop that uses a big belt sander and would be willing to give you the worn out belts. I've seen new ones in surplus places that weren't too expensive and never gave a thought to using them for asphalt. I won't pass the next ones up so easily. As far as heating that styrene would one of those little pencil torches work?
