I have a friend who asked me to make some dinosaur bone replicas for him. The goal is to bury them for a few weeks/months and then the kids in his classes will dig them up as part of a project. I'm thinking of going the route of pink foam insulation sheets. I'm good with the actual shaping and carving but I'm unsure of coating them to last. I've read about a first coating with wood glue or gesso, then maybe rondo for the final coat before paint. I've also seen maybe Portland cement. For reference, I'm thinking the biggest bones would be a few feet long, maybe 8-10" diameter. Has anyone done this before or have any advice? As this is a side project for his students I'm trying to keep costs down. Thanks in advance for any help!
