I really wish you had asked about sodablasting the deck and sandblasting the spars prior to doing so...
Sandblasting aluminum is usually a mistake, as is sandblasting stainless steel used in a marine environment. Generally, you want as smooth and fine a surface on the stainless, as scratches, like you get with sandblasting encourage crevice corrosion. Sand is too abrasive a medium for either material IMHO, at least in a marine environment.
As for sodablasting the topsides and deck... It is generally a mistake to do so, at least from everyone I've spoken with, including the guy who did the sodablasting on my boat. I am surprised that the sodablasting vendor didn't warn you about doing so....
BTW, any form of air-blasting media can generally etch or damage the surface if not used properly. However, some media, like soda, corncob or walnut shell, will tend to be far less aggressive than sand.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
