Veneer Application
Should I apply a coat of shellac to the glue side of a piece of veneer before gluing it to the substrate so as to prevent glue bleed through?

I would be concerned about the shellac keeping the glue from holding.
As Dane, I use contact cement.

What kind of veneer & what kind of glue? Traditional sawn veneer is thick enough to prevent bleed-through of water-based white & yellow glues.
Contact cement is popular with the thinner veneers but might not be strong enough to flatten ripply natural veneer unless you use many clamping cauls or a vacuum bag press.
Also many thin veneers have a backing that lessens problems with cracking, glue bleed, or finish bleed attacking the glue.
Shellac is a good barrier to prevent all these problems.
