Hi Mark,

Try Micro-Mesh.  It is various grades of cushioned abrasives, that I used to
use for polishing scuffs on my army helicopter's windshields.  I think
Electronic Industries still stocks it.  Or talk to Basler Aviation on where
to get it.  They also make a metals version of the plastics kit too.
