Paul,
I will apologize to you.
I don't know what the answer is to your problem as I have never experienced it in my use of BLO & CA.
I have seen many discussions on SMC concerning pen finishes. Some of those listed have been shellac based finishes, plexiglass dissolved in acetone, CA, Blo&CA, lacquer and others I am sure I have accidentally overlooked.
As I first stated and others stated after me, take your time, try different methods, find one that works for you and stick with it.
Again, my apologies.
Ken
So much to learn, so little time.....
