The really tight areas make it tough to get a glue gun in and out. My pep so far did ok but all those little misalignments turned into nasty warping. I may make this piece a damaged peice. Or replace it altogether. Still kinda torn between h3 and h4 armor. They don't appear to be more complicated then one another but the 4 is defiantly more focused on the undersuit but looks more realistic where as 3 seems a bit cartoony to me. At least in the helmet. I'm tempted to do a 3 4 combo
