Hello guys , I gotta a problem with some vintage pens i got , and i believe that i made it worse. I think i screwed them too far an the plastic trying to stop leakage through the treads. the plastic developed hailine cracks on the section and of couse , leaked more. the thing is , how can i fix it? i thought i'd had the answer. Superglue! . didnt do the trick and now i got some ugly blobs of superglue resin on the section. is there any salvation for me ?
