So, did you ever get your Neotec back? And, if so, did they fix the water egress issue? I ask because I sent my lid into Shoei earlier this week for the same problems. I was told by Shoei's CS that the "fix" would only take a couple of days (something about letting glue dry before sending it back). They received it Tuesday of this week (3/5) and I haven't heard back from them. I'll give them a call this afternoon, but wanted to see if you ever got your issue resolved.
