A method for surgical planning is disclosed. The hydrate has a defined number of moles of water of crystallization and possesses better storage stability and dissolution characteristics than conventionally produced hydrates of such acid addition bis-salts. In the first position, the bias system applies a maximum effective bias rate to the reciprocating system and the retention system applies a holding force upon the spray boom to maintain the spray boom in a desired outward position. In some embodiments, an impermeable sheet of material may also be placed over portions of the composite material to compress it against the SMP apparatus.
