I wonder if it would 'clean' up plastic parts. For instance, the targa cups in the trunk tend to get a greyish or yellowish tinge to them after a while. Maybe this would whiten them up?
Rob, the yellowing in plastic parts is internal due to internal changes IIRC from what my Dad the petro-chemist told me - he passed 12/08 so I can't ask him again, or wouldn't get an answer even if I tried!
So blasting shouldn't change that discoloration much, except at the surface layer crud level.
