I've been happy with the results from Hope's pure tung oil on my last two projects, which were english walnut and curly maple. Found the stuff on Amazon. I may try rubbing in some Birchwood Casey stock wax on one of my test pieces to see if it shines up just a bit. I've had this oil for at least two years now and it's still as thin as the day I bought it. I store it in one of those collapsible water/wine bladder bottles and squeeze all the air out.
Same here. I bought a bottle of Hope's pure tung oil off Amazon for an 870 stock and forearm. The shipping took for-friggen-ever, but it was worth the wait. Can vouch it is good stuff.
