Hello everyone I am going to build a helmet,using pepukura, as a practice for my main cosplay but i need some help I have no idea what to use for resin.However for bondo im using isopon p38,which is a polyester filler.What do i use for resin? Im so confused lol. I also see people on youtube completing the fiberglass and resin section then creating a mould around there product. What is the purpose for this? Do i need too do it? What kinds of paints do i use? I want to give mine a worn and torn look,likes its been in war. Can someone just run me though the process,step by step, starting at the resin/fiberglass/filler stage then ending affter the painting stage.
