we are starting a dual build now in the hopes that we will have an Iron family halloween this year. I am using closed cell foam in the 1/2 inch gym flooring and foamie materials. some mare eboxy surfboard resin and a whole lot of glue sticks. We need to step it up so we can show up my son walking down the street in his War machine suit. I will be posting pics of this build as it develops. We only have under two months but my daughter has come on board as a builder apprentice so hopefully we will prevail. We decided to nix the pink/yellow paint scheme for he suit and will be match the paint to the original mark IV for her fem suit. here is a pic of my son's completed suit.
