Thanks for the awesome tutorial! I'm getting ready to make an ODST helmet (start with something that looks easy), and I was able to find every resource I needed at a Canadian Tire (fibreglass resin, liquid hardener, and I'll get the fibreglass cloth soon) and a Michael's (brushes, the paint I'll be using, some see through plastic sheets and some interior stained glass paint), so this is going to be a pretty fun project. Sorry if it's been asked, I've looked around and either overlooked these questions or didn't see them, but..
1. The fibereglass cloth on the outside is just personal preference, right? You can just use it inside for the sturdiness and it'll be fine?
2. If you use the fibreglass resin and liquid hardener on the outside, do you need anything else, or are you good to sand it and paint it once the inside is re enforced with the cloth?
and last
3. Do you fibgreglass cloth the visor area, then cut it out with a dremmel and put in the actual visor you're using?
Thanks in advance, again, sorry if these questions have been asked.
