sorry guys, but the wood stock is staying on. Maybe I can lightly sand it and reapply some oil?
That's exactly right -- your rifle has a polyeurethene finish, and moisture under the finish is causing the clouding. Strip it first -- that is, apply a chemical stripper -- to minimize the sanding needed. Then finish with increasingly finer grades of sandpaper, raising the grain (dampen with a cloth, then gently heat) between sanding sessions. Finish with oil -- you could use tung oil, or any of a dozen commercially available finishes.
I have a Kimber M82 .22 that has had literally hundreds of thousands of rounds through it -- it's about as old as your ADL. Thanks to its oil finish, it simply shows a high shine where the hands hold it.
