Sintra?

Hey,
What do you guys use for the armor plates and how do you mold them?

I've heard that a lot of people use sintra, but I don't know what that is.

Please give me some help, I'm desperate.

Thank You

It's a sheet of plastic that is sturdy but when you heat it up with a heat gun you can shape it pretty easily.
