Yeah, that couldn't hurt anything. You'll be able to see what, if any, finish is left too. If it soaks into the wood, then you know the finish is gone, and I would put on another coat of oil in a few days. Just something to protect it from the fluctuations humidity, and exposure to weather. otherwise you'll end up with warped and/or split stock. I had a SKS years ago, the wood in the stock, nor it's finish, were its strongpoints. Good Luck
