chambers oil. mix 50/50 pure turpentine. apply 2 coats drying between each, then a thin coat of pure chambers and let dry,,,,,,,,,,,,,,,,
Hmm. Must not be Waterlox after all, I recently did one with Waterlox original sealer/finish (tung oil, phenolic resins, 75% paint thinner, and some linseed oil) and it was the fussiest stuff I've ever used bar none. Too much thinner, it flashes off in 15 seconds and leaves an oil so thick it won't hand rub. Have to put it on in sections and wipe off with a rag, time it carefully or you have a mess. Don't use that stuff, it ends up basically like Tru-Oil but takes literally ten times as long to get the same results.
I hate Tru-Oil but it does a good job and makes a durable finish, I just don't like how it feels. Properly "boiled" linseed oil (which cannot be bought, must be made and the driers must be made from scratch, too) is my favorite stock finish and easy to apply with a couple of bare fingers.
Maybe a crash course in finishes is in order.
There are "drying" oils like BLO and pure Tung oil, those dry (or slowly polymerize) by reacting with oxygen in the air. Metallic trying agents are added to speed this up and heat also speeds it up. These oils penetrate because they dry slowly and really show the grain but never get hard, don't build up on the surface, and often take seemingly forever to dry (literally weeks between coats in some cases).
Next we have varnishes. These are drying oils plus resins like phenolic resin or pine resin. They appear to dry faster because the resins cure on the surface and let the oil soak beneath. That's oversimplified but basically the gist. Varnish can also be made with polyurethane and other "oils" combined with resins and these dry very quickly, as in overnight for a brushed on coat and hours for a rubbed-on coat.
Polyurethane. Does not penetrate well, dries fast, builds up on the surface fast, fills grain fast, chips easily, and is solvent-borne so it shrinks when it dries unlike drying oils which EXPAND as they dry. Not a lifetime or heirloom finish but the easiest to work with in my opinion. Spar varnishes are often poly/solvent based with UV blockers and hard resins added.
Shellac. Not weather resistant but is an effective moisture barrier, often used under a drying oil to seal the stock just like a vapor barrier installed under the siding on your house.
Lacquer. No place on guns.
Epoxy and catalyzed urethanes: No place on guns IMO.
Minwax makes a wipe-on polyurethane finish in gloss, satin, and matte and is probably the easiest thing to use, but is not anywhere near historically correct, does not feel good to the touch, and will eventually crack, yellow, peel, and doesn't show grain like BLO or Tung oil.
As much as I hate to recommend it, Birchwood-Casey Tru-Oil is probably what you're looking for if you're new and just want something foolproof that works. Don't follow the directions, though, dilute the first coat or two with paint thinner (real, mineral spirits, not that milky, water-based California foo-foo juice), drench the stock and wipe it all off before it gets sticky. Steel wool smooth between coats with 0000 or finer steel wool. Tack off with a rag and mineral spirits after steel wooling it and apply final coats a few drops at a time, rubbed in well with the fingers. Buff it with a lint free rag before it gets too sticky and let dry a day between coats. If it's too shiny for you in the end, rub it back with whiting, pumice, rottenstone, or 000000 steel wool until it has the sheen you like. If you dull it too much, hand-rub on another very light coat and do it again.
