Hey guys! I have a leaking Ion too. It's been like a month since this problem started and its killing me. I just started playing paintball in October 2011 so this is my first paintball gun and I really saved up for it. Frankly, I don't have money to spare to by a new one so I've been looking for other ways to fix. I found one a few hours ago and I'm not really sure of it. The write-up talks about disassembling your Ion and cleaning it with a something called like an ultrasonic cleaner. Has anybody heard/ tried that before? I think the source is credible because it was written by a doctor. BUT STILL it is better to be safe than sorry. lol.
