----- corn syrup ought to be water soluble. Otherwise, I think that this may 
be a stereo microscope job. I use diminutive tools to my own designs, and if 
you probe along a groove where it meets the edge of the stuff, you observe 
carefully while trying to get under it. At microscopic dimensions, everything 
is soft; vinyl is like butter, so is aluminum of the kind used for pre-
grooved records. Even the hard stuff will display observable flexibility. 
When you lift the stuff; which is likely to be translucent, you will see 
optical fringes due to the distance to the lacquer created. Try to see if you 
can pry it loose, or if it holds on to the lacquer. If it does, you need 
agents; paraffin might do the trick. WD-40 might do the trick, but if you are 
going to use it on records, try to see in the microscope what happens to the 
lacquer under a droplet of the liquid (goes for anything you might want to 
try) on an unrecorded bit near the label. Dependent on the area involved be 
prepared for many hours of painstaking work. Have fun, or call in the 
Incredible Shrinking Man.

Kind regards,
