I'm probably not applying the oil properly, because if I leave metal parts on the rifle, and some stay naturally like nose cap, inlays, etc., I get a build u-p of the finish on the metal. I have to steel wool those parts after I'm finished to get the hardened varnish off the metal. The varnish kills the polish and has to be removed IMHO.
I'm unhappy with Truoil. I find that it does not wear worth a bean. And the stains then leach out of the wood creating a mess - light areas of muddy colour.
I have to find a more durable finish, and go to AF for stain. I used to use Fiebing's Leather Dyes to stain my maple stocks, and I always got super definition of curl and a great colour. The dyes seemed to remain in the wood better than Laurel Mountain Forges Stains too. The only drawback is that they are U*V sensitive, and bleach out over a period of several years. I would love to hear from others who use their rifles a lot under all weather conditions,and who don't have this problem.
