For the Parkers using the pliglass sacs, I have seen two different adhesives recommended when replacing the sac, Shellac or clear nail polish....
Which is correct, or better if either can be used?
I have a slimfold that well best non technical term for the sac is gooey. No idea what caused it to be that way but when I took the pen apart I peeled that sucker right off and chucked it... and a Parker 21 that looks like they used some sort of permanent black ink in it, so for esthetic purposes I wish to replace.
Thanks
