It is very hard to sand it smooth. Also, when you go to melt out the foam with acetone you get a gooey sludge of the foam as residue that has to be cleaned out of the part. Messy business, at best. At least this has been my experience with the stuff - and also with the blocks of green foam that you can buy at a hobby store or WAL Mart. Best to take some time and make a good plug from non meltable foam or wood or plaster of paris, then wax hell out of it before doing the layups.
