Spent a lot of time last night working on the shoulder pieces. I am attempting to use expanding foam inside the fiberglass pieces, carving out the space I need so they will rest on my shoulders. It is proving to be a bit more of a challenge than I initially thought. In the above photo, I added more foam after carving out a little to much while trying to figure out the proper fit.
I also applied the first (of many) coat of black gesso primer to the breastplate. The plan is to complete about ten coats, then sand it smooth.
