So I've got a question for those with experience in mold making and vacuum forming.
I'm currently working on a helmet scratch build. From paper, to resin, to Bondo. And now I'm about 50% (IMO) done as I continue the arduous task of sanding and "fine" sculpting Bondo.
Here's my questions:
I've seen on YouTube an armorer (the naked trooper....) pull forms using plaster as the final mold after the initial sculpt of clay. Now I've read on different forums that plaster is easy to sculpt, sand and get smooth but the durability is low. Anyone have experience plugs out of plaster and their durability?
Secondly, if I do use plaster can resin or Rondo be coated over it for added strength?
Lastly, would it be better to sculpt bucks out of plaster, then do a cast of that plaster and then do a pour in mold of that fine detailed cast with a highly durable medium ( similar to what AA does with aluminum, fiberglass strands, etc...)?
As always any help is greatly appreciated.
