I just got a Nexus3 that I ripped the neck seal on while trimming and was going to DIY replace it, what cement do I need to use? Contact or Aquaseal? Do you sell the seals separate or should I just get a standard Latex from 3rd party?

P.S- I ripped it by not turning it inside-out and putting too much tension on it while cutting. Learned that lesson

Hey vshearer, the pre-ferred method of replacement would be to get a replacement neck seal from your local Whites dealer, This is the easiest way to avoid losing your warranty. If you do decide to use a 3rd party seal, ensure that you do not attach outside the parameteres of the tape connected to the suit, if this happens the warranty will no longer be valid. Hope this helps, if you have any other questions please let me know.
Thanks Doug,
