Hardening Bridge Caps

[David Love]

When cutting a new bridge cap I typically paint on a low viscosity epoxy to
both harden and seal the cap.  I do this after drilling and notching but
before pinning, sanding back the bridge top flat again before inserting the
bridge pins.  

I'm considering doing this same process with a thin CA glue which seems like
it will offer some advantages: cures faster, wicks into the wood better,
requires less sanding afterward.  

Any thoughts on the differences in terms of providing a seal and adding
density to the wood between the two substances?
