Sorry to necropost, but I thought it'd be best just to keep this thread updated.
Over the past few days, I fiberglassed the helmet's exterior. I still need to sand down all the rough edges and give it a once-over with my power sander, but that will come in the next few days. I'm currently out of school for my Christmas vacation, so I hope to get some notable work done on this helmet by the time I head back to classes. By the way, the plan is still to do casts of this helmet, and depending on what kind of money I get for Christmas, I may get to mold it up sooner than expected, but I'm not going to rush into that by any means. It'll be my first full-helmet, two-part mold, so I want to do it right.
Super commandos beware. The Death Watch are coming!
