I was going through my archery box and noticed that I have several hundred (nearly five hundred) 4" Fletch-Tite vanes. I remember reading that Bohning treats their vane bases with some sort of chemical in order to improve adhesion. Will this chemical expire? Will vanes ever expire?

Thanks

Being put away in your house and out of the weather they will last for years and years.

Yep. Besides, if you're worried about it, clean them w/ alcohol and use a good glue. They'll stick, I assure you.
