So I too originally saw Xrobots technique for plastic coating foam and thought wow that looks great I should try that! Sadly after getting smooth on 65D (for much more money than I hoped to spend as that stuff is expensive as heck), My results were less than those seen in the video. I had issues with peeling the plastic up in sheets and also an extremely rough and at the very least wavy unsmooth finish. I thought I did everything correct, 6 layers of diluted PVA, brush on equal parts A and B of 65D, and yet it came out terrible leaving me trying to sand a mess, peeling sheets or plastic, or looking at the small small sections where it did go on relatively smooth, and seeing the coat was extremely light and also uneven in thickness! I tried doing multiple light layers but even at 3 coats it never seemed to go on evenly to the clean white coat that seemed hard in xrobots video. Your armor is beautiful and obviously it seems like you've mastered the technique so maybe you can tell me what the hell I'm doing wrong? In an effort to get the smooth results I want I resorted to turning the foam into a type of base for a typical pep build (fiberglass inside, bondo outside), but even now its still not the baby smooth I seek. As I have some smooth on left and potentially invigorated by your amazing build and results maybe you can offer some insight as to what I did wrong, and how to do it right??
