It seams like a good product. I tested it on a piece of scrap foam and it sanded easily. It will crack with the flexing of the foam if you press to hard.
Works like magic. Just use a flat soft spreader and you can cover any surface faults in no time. Fast setting and easily sanded. A marvellous product for model building.
