I just inked up my 51 and it writes great. When the cap is pulled off, however, there is ink all over the barrel. I have cleaned out the cap and wiped off the barrel but as soon as it is re-capped and the cap is removed there is ink all over it again. The first time I pulled off the cap ink droplets flew everywhere. Is this a normal 51 problem? Is it possible I over filled it? Starting to get pretty messy.
