Hey guys, my first real thread. I plan on building some paper tank models for use in Warhammer 40k, and I definitely want to use something to strengthen the cardstock. I am familiar with working on pepakura armor, but I have never done the fiberglassing or resin for those. I know Resin though would ruin details on a model that small. Do you guys know of any kind of spray hardener that would make the exterior of my model paintable as well as giving it some durability?
