Sandblasting

["Edward Hamilton" <hamilton@ptd.net>]

My GT6 frame is about ready to go to the sandblaster.  The ends of the frame
are "capped" off.  So, should I assume the frame will come back with 20+
pounds of sand inside it?  I doubt that I should expect the blaster man to
remove it, so...how do I go about getting it out or should I attempt to plug
all of the bolt/misc. holes first?
