Gotcha, I have a Bare and a Moby's dry suits and have not had to replace any seals on them yet....YET. I had on older suit a while back, I think it was in Imperial. Replacing the seals on that SUCKED!!!! I actually don't think I ever did finish and ended up buying my Bare.
Anyway, no matter what I am thrilled to see that companies are starting to address the dry suit seal issue as it has been an ongoing problem that no one has seemed to even come close to perfecting yet.
