This is if you are starting out with a finished stock, as I believe you are.
If your stock gets wet while hunting or shooting dry it when you get in. When it gets good and dry, inside as well as outside, a couple of days at least, perhaps a week, put on a couple of coats of a good wood wax that has been mentioned, Butchers or Johnsons. No problem on waiting until the end of the season, just wipe your stock dry each night until then. After you treat it with the wax, if it gets wet while hunting don't worry about it, just wipe it dry after the hunt. The stock I just got appeared to have been left damp for a while, it's OK now though, it was not to bad and the wax has filled all the imperfections on the finish and sealed it. Never wax or seal a damp or wet stock or piece of wood, the finish will not stay on....<><.... :grin:
P.S I really doubt that your laminate stock will come apart from becoming wet, nowadays with the new glues, and the heat and pressure used in manufacturing laminates, those glue lines are stronger than the wood!! The finish may become porous or cracked but that is an easy fix....<><.... :grin:
