Anyone know what the new Gen 3 plastics are made of yet?IMS tanks are made out of polyethylene. Gen 1 plastics are all made out of polypropylene (if I am not mistaken. I would have to check the recycle code, but that's what I recall.). If I am mistaken on that, then they are made out of polyethylene, so macht nichts. Gen 2 fairings and tank shrouds (you know, the expensive shit that breaks easily) are made out of nice, brittle ABS.
