Although I said I wasn't going to do it, I may reinforce my SgtFang Mystery Helmet with fiberglass, primarily since I intend to install HyperDyne's servo system into the lightweight helmet. I'm worried that the weight of the servo system might be too much for the helmet.
For those with fiberglassing experience, what should be on my shopping list? Where can I buy the supplies? What are some hurdles I might run into?
