I did 2 layers of glass on the outside and had no problems with them conforming, use small pieces cut to the area you are going to cover, any autobody tech. should know how to do this so if you know one recruit them, or even an airframe mechanic that works with the latest composits, this is where I got my experience building cars and repairing aircraft. also I did not glass the inside of my helmet, just 8 ounces of resin and rotated it till th resin took a set, glass the outside twice, spray foam on the inside and a coat of resin over that, now mud the outside per the tutorial and detail. the real helmet is not suppose to have all the angles the pep helmet does.
