I've got several Boyd's stocks,and have finished everyone of them myself. I use Tung oil,and always hand rub 10 coats of oil on the stocks,and wet sand between coats using tung oil and sandpaper to wet sand it. A couple of the stocks are at least 10 years old,and I've never had any problems with them spliting or de-laminating.
Whoops.
Txhillbilly, didn't see your post on how to put on tung. Well said. Sorry I was redundant.
