I find that the firt thing to do is brush in a little stain as was used in finishing the stock. If it is a factory finish, I'll bet it still needs some stain.

I then use minwax wipe on poly. Apply a thin coat with a toothbrush. If need be, apply a second thin coat.

PS I am a big fan of Minwax wipe on poly. I use it to cut the truoil. I figure the poly gives the truoil a true waterproof finish. I have had great luck with this combo for finishing stocks. I am just a beginer though....
