Gilding the lily.

Don's right, if I understand his metaphor?

That wood hardener only works on the outer few thousandths of the wood... much like "boning" a baseball bat and because most arrows are made of a soft wood to start with, it won't help much I'm afraid.

That's why most footed arrows are footed with some type of hardwood like ipe, purple heart, etc.

what ray said.  wicking in any kinda glue, hardener, finish, etc, just goes to a slim outer layer and the innards are unsupported.  gotta foot the arrow with something internal for realistic functional effect.
