Soda Blasting

I'm repainting a fiberglass airplane.

Sanding the wings, once removed from the plane is a fairly easy chore, however sanding the underside of the fuselage and strakes is going to be a major chore.

A body shop near the airport has a soda blaster that they will let me use. I've heard of folks using these to remove old paint from boats and planes.

Is it possible to use a soda blaster to remove only the top coat and not remove the primer and micro beneath??? Basically use it to do the 60 grit sanding job and then follow with the relatively easier 150 and 240 grit sanding to prepare for primer?

Anybody do this and actually save time and effort?
