I am working on an Iron Man project as outlined in the Sarlacc Pit. It is being carved out of blue styrofoam, the type you buy at a home improvement store for insulation. The I am adding the nesessary details to it, I feel that in ourder to fiberglass a negative copy I first need to add bondo or some other smoothing agent which can then be sanded to perfection then waxed and the whole 9. I have some of the materials at home so I can test it out, but what are your thoughts. How would you proceed? I want to make a negative, and then a positive from fiberglass to make the actual helmet.
Has anyone used the blue or pink foam before? Thanks in advance for the help.
