I heard you need advice on fiberglassing, well I think I can help. Whenever I fiberglass I start out with an outside basecoat that has the exact ratio of hardener to resin. I apply it to the outside and let it sit for a couple hours after that I do the same process over again. once I have two coats (this is were it gets messy) I mix up a large batch with about 1 1/2 times as much as your suppose to use. This makes it dry much faster and I slush it around on the inside of the helmet trying to cover everything evenly.
