Vicking, the Trueflight website also talked about some waterproofing products available. I wouldn't recommend any kind of hair spray. My experience with hair spray is that is binds my hair together. That would be conterproductive to feathers. If they hit something such as a rest, riser, brush, etc., the arrow will deflect instead of the feathers folding. Especially as a traditional archer, my arrow wouldn't even leave the bow before getting messed up. I'd recommend going with one of the marketed products or some unscented talc powder. The purpose of talc powder is to absorb moisture, so whether feet or feathers it should work <img src=icon_smile_big.gif border=0 align=middle>. I'm not completely sure, but a bottle of fletch-dry (not even sure it's called that), is around three of four dollars and will handle about three dozens arrows. I've never waterproofed my feathers before, but have payed for it when in the rain. I should take my own advice and look into it.

God bless,
