now you're starting to get into the grey area where it begins to be more trouble than it's worth. there are a few things you can do with the rubies that will strengthen it up (metal craft ring, a real lens) for relatively cheap. but due to the innacuriacies of the rubies bucket, fiberglassing it will probably be more expensive than the helmet itself, and (imho) overkill to protect such an inexpensive investment. i would suggest going the craft ring and lens route, use it as a practice piece for painting, sell it on ebay (or here in the cargo hold) and use the procedes from the sale to buy a fangs.
