Going to be delving into my first bought of armor making soon. I keep hearing about how amazing wonderflex is then I'm told that sintra is where it's at.

However, the armor I want to make will need some domed pieces here and there and I heard sintra can only bend in one direction like around in a gauntlet shape. Is this true or are there ways to make sintra mold into any shape you want?

Then general plastics/armor
