I reinforced a Bradleyfett helmet and some Ruffkin gauntlets that I had to modify for my wife with fiberglass recently and was thinking I'd like to seal the inside with a nice lining. I love the lining inside the FPH and was wondering if anyone had any idea what that is...

In the FPH build-up thread, Fettpride refers to it as a "white epoxy coated lining". Any clue where I could get that and is it simply brushed in?
