Strengthening Foam Armor?
Here's the story, I'm working on making some armor out of those thin foam sheet things (Foamies? I'm sure you'll know what I'm talking about). It's for a Thor costume.
I've sealed and painted all my armor, and it's strong...sort of.
But I'm worried about accidentally making dents in the armor still. I've already accidentally left a fingernail impression in it.
Any ideas on some type of coating to put on it so it's really, really hard? I'm not very careful and I'm fairly clumsy.
