Hank.. given what your thinking...
IMHO PURE tung oil is the way to go..... Tung oil doesn't really "dry", it actually "cures". six of one, half dozen of the other I suppose. But you can build up a finish with Pure Tung oil. Just give plenty of time to cure between applications. Follow mfg's. instructions closely! Usually a week between coats is safe. PTO is kind of like polyurethane when applying multiple coats. One coat builds atop of the previous coat. Kind of like having two distinct layers. Whereas a lacquer melds with the previous coat. Here two applications will give you what amounts to a single layer. Type of application can vary from right out of the can to diluting the first coat with mineral spirits/turpentine and then applying successfully 'purer' applications (less thinner). Sanding lightly between coats.
Be careful sanding between coats of PTO. You can sand too far. When you do, you get what is known as ghosting or witness lines. This happens when you sand thru the upper layer and into the layer below.
by now, you should be getting the idea.
Do your homework. Bob Flexner wrote what I consider one of the best books of finishing: "Flexner on Finishing"...its a good read, not overtly scientific, rather a more practical approach to numerous types of finishes. A little history and alot of how-to. A book you will reference to for years to come.
A good high grade furniture wax for a top coat will work fine. Carnuba is good stuff, but costly when compared to others. Minwax Regular finishing wax and clear Briwax are two good choices I like, Claphams Beeswax is good stuff but ore suited for food grade applications IMO...
OH, btw.. yep... use a blotch control/pre-conditioner!
It ain't rocket science, but you do have to follow a specific schedule to achieve the best possible finish, regardless of what you do. Spend a little time and do some reading up on what you want to do. Gather your materials together and get some leftover scraps from your desk to experiment with. Cut up some test squares and have at it.
Got any questions along the way, dont' hesitate to ask. Alot of folks around here know how to throw down a great finish. Their more than happy to share their knowledge with you.
