Preemptive CA in bridges?

Re notching and re pinning existing caps, I've use CA after 
the new pins were in, and been quite happy with it. Driving 
pins in a new epoxy laminated maple veneer cap, I use epoxy 
for two reasons. First, it's slippery and makes it easier to 
drive the pins. Driving pins into this type of cap is 
difficult without something lubricious added. Second, I'm 
inherently terrified of the thought of standing over CA soaked 
ANYTHING and hitting it repeatedly with a hammer.

Who cares about it's shear strength? It's in compression in a 
wood matrix in this application, and would almost certainly 
make a positive difference in long term deterioration of the 
cap. I think it's a good idea too.
