I was thinking the same thing w/ polyurethaning, doing it like the thick tabletops. Set it on a smaller pedestal and Pour it on, and let it drip over the sides. Apply multiple coats. Would be solid and smooth.
I have wondered what was used to make the vintage red ovals. The first 1954’s up to the last 87’s don’t seem to fade or crack and are relatively rock chip proof. They last forever as long as you don’t hit them with a hammer. They are some kind of baked epoxy enamal. You see 50, 60 and coming up on 70 year old Petes with vintage emblems still in great shape. The emblems that they started using around ‘88 fade quickly. Must be something that got expensive to make or outlawed by the Epa. There have been a few enthusiast discussions on this over the years but I don’t recall any of the Pete historians finding any clues.
I would use acrylic urethane. Thin layers until you achieve the thickness you want. I would test it on something similiar as to not screw up the emblem.
