I recently received a Pilot 78g from Goodpens here on the forums. I was thinking about converting it to an ED because it is my favorite for all my long writing sessions (Essays and minor research on wearable technology). The squeeze converter doesn't hold enough ink and refilling so often is kind of a pain. I have seen older posts here on FPN and Badger and Blade about it and it seems all you need is a pen body with no holes,an o-ring and silicone grease. I have the first two but have looked at my local hardware stores and I can only find the silicone-based caulk which i know is advised against. Can you use something like a organic beeswax or Chapstick( a wax based lip balm)? I am very new to these things so any advice offered would be appreciated. I look forward to some help and suggestions!
