35 years of experience in weird laminating, veneering and exotic adhesive use tells me that most advise here is good, but will add a few points: Contact cement is great on thick veneers like this, as long as its layed on thick and pressed thoroughly, but long grain spring back like Sean did is a little questionable, so glad he epoxied (I pictured the grain going opposite direction). Epoxy only needs veneering on one side. The old law of veneering both sides only applies to glues that shrink, or glueing to solid wood. Veneeriing one side of ply with epoxy is fine.
The nice thing with epoxy, is that if Sean got voids from uneven pressure, he can syringe epoxy into the voids later.
If you ever do this again, its much easier to veneer your curved parts ahead of time, while bending at same time. It doesn't take long at all to make a bending form, then glue up the bending plywood (3/8" bending luaun or multi layers of 1/8" BB plywood) and the veneer all in one glue up. Use a stiff caul over top made from 3/8" plywood faced in 1/2" styrofoam for even pressure, with 2 x 2 cleats on long edges to clamp at edges, no need to clamp middle as the stiff caul will be adequate pressure with epoxy.
You can see the similar shape in the pcs below, and I used a 2" long flush trimmer to clean the edges prior to sanding, and made a custom hand held 6" DIA drum sander for sanding the concave surface (Upper central part of last pic).
