I am working on some proton packs for me and my friends for halloween. I just finished making the positive mold and will be starting the rubber negative when the supplies arrive. I plan to make the shells out of fiberglass, but instead of buying the small packs from the automotive store I was planning to buy bulk online.
Does anybody know what weight of fabric is equivalent to the bondo fiberglass or what is best for making a fiberglass shell from?
Thanks in advance
