'60 Valiant Wagon - Trying to find interior color for rear storage area

I'm not sure if you're doing a totally original type resto, or making a Hot Rod....but I'll share what I did in the back of a 64 Belvedere wagon that was more of a Hot Rod. I took all of the cargo area floor parts to the local Rhino Liner place, and they sprayed it inside all the indentions where the old Masonite stuff from the factory went. They built it up until it was slightly higher than the surrounding edges to keep them from getting scratched. It turned out awesome. They can do colors, and as an added bonus it keeps stuff from sliding around in the back. Good luck with your little wagon.
