It is in composites where the problem of different
expansion and contraction rates come into play. The military
application of composite materials to many skinned surfaces
was not a good market for "ice blasting". The private sector
is going toward the increased use of micro-composites also.
Steel bridges and engine blocks are fine for the ice method,
I was just saying the use is limited to homogeneous materials.
