I want to build something similar to this: http://machine56.deviantart.com/gallery/#/d29rnw0
1.What is the cheapest brand without sacrificing strength or detail? I don't want to spend so much on just one helmet if I don't have to. Also, which one would be the easiest to use? What makes casting resins difficult in the first place?
2.How thick does it have to be to be strong? I never could find out how thick everyone makes their castings
3.Can you use silicon caulk for a replacement/cheaper alternative to a rubber mold? What about plaster of paris?
4.Does any of the brands give off fumes/an odor before/after they cure?
5.Which one is good at being sanded/drilled/cut with a dremel?
Paper mache clay:
1.Has anyone ever tried this? (If you scroll down you can see my posts with the same picture from above) Any suggestions on this or paper mache period?
1. I've heard that even after it's cured that it gives off strong fumes. Is there any way to avoid/remedy that?
2.Can you seal the fumes using primer spray?
3.Are the fumes harmful?
4.Can you wash the fiberglass piece to get rid of the smell?
***As a side note, is it cheaper to do fiberglass than using casting resin?
