How to make Spartan Armor from cardboard

Step 4 Fiberglass

this step is optional, but very benefitial.
The fiberglass will add an extra layer for strength and smoothness that will protect against cracking.

When you get the resin it should come with a little tube of hardener compound, and with that directions for how much of each to combine. if not it's pretty forgiving as long as you use enough of the hardener.

and you can get either the sheets or matting,they'll both work fine, but I think the matting works better for this project.

once you mix the resin with the hardener you won't have very long to work with it untill it becomes very stiff, so it's best to have your peices laid out and ready. I even had torn little wallet sized squares and mentally placed them on the peices.

first you should put some resin on the cardboard itself so the fiberglass has something to stick to, then mash the fiberglass squares down using a brush with more resin.

Everything will get really sticky and tedious but hang in there it'll work out just keep mashing the fiberglass down with the resin.
if you are having trouble with the fiberglass staying in little crevises use more resin, and try to get rid of all air bubbles.
