Finally took the butt stock off my 99F after and the forearm got very wet. I had previously polyeurothaned the forearm channel, & it was fine. But the finis on the outside of the forearm & to a lesser extent the butt turned a pale color, and the forearm swelled. The interior of the butt stock is unfinished - just bare wood. So I might as well refinish it all. Since I have polyed the forearm, should I continue this on the outside? Should I then also poly the butt stock, and are there issues with doing the interior? Thanks for your help.
