I'm working on the tailgate of my '58 Fleetside. The panel that says "CHEVROLET" has spot welds around it and I'm wondering if I should fill the spot welds as I'm filling the rest of the dents in the tailgate or were the spot welds visible when the truck came from the factory? Also, should I use seam sealer going around that "CHEVROLET" panel within the tailgate?

Thanks for any advice.
