I ended up ripping the right seal on my drysuit again. That particular silicone seal had 87 dives on it. The one before that ripped with 80 dives on it. The original left wrist and neck seal are still going strong with 168 dives to date. This makes me question what exactly is going on. Do I have a different removal technique on my right wrist that is more prone to ripping drysuit seals? As a second non scientific test I've been using baby powder (unscented) to see if it really does shorten the life span of a silicone seal. I started using baby powder on 12/14/2012. I'm curious to see what happens.
