Nice work so far man. For painting the foam I used PVA and found it peels off too easy and just undercoat mine with plasti dip. One thing though I think you are using the foam that has a lot of air in it. I have seen someone else use that type of foam and he said he sealed it with PVA first then plasti dip. If the foam doesn't have a nice smooth surface like the type I have been using then I believe PVA is a must. Can't wait to see this suit painted up its looking sweet so far.
