I have a thirty year old Sailor 1911 model fountain pen with a fine point. I love this pen, but if I don't use it for a day or two the nib dries out even with the cap tightly sealed. I was wondering if there were something -- such as silicone -- I could put on the cap threads to prevent this from happening. I have some inexpensive Pilots and Lamys that will work perfectly even after being in a drawer for a couple of weeks and I've noticed that these pens have caps that seal really well.
Any help will be very much appreciated
