Working on a Traditions Kentucky rifle kit. I believe the stock to be made of beech wood. I'm told with beech that water based is the way to go, but I did a Deerhunter beech stock a few years ago and it turned out great with Minwax oil based stain. I used a mixture of walnut and red mahogany and got a nice even reddish brown, med. dark color that really "popped" after a few coats of Tru-Oil. So why Water based and why not oil based ? -Thanks
