[Northkeep] Longbow Wood treatment

[Gisela]

OK, now that I know I can save my leather watch band by using oil products,
it reminded me that someone told me a while back that I needed to keep some
sort of oil product on my long bow... However, I can't remember what they
said to use. I want to say it was some sort of leather care product, but I
could be wrong... it happens...
Anyway, any advice on keeping my crossbow in good shape?

Danke!
