Can a friction shellac finish like Mylands brand be used over a dried tung oil/Danish Oil finish. I,m looking to give a little more gloss to the finish after about only 2 coats of tung or Danish Oil which are rather dull.
 
Shellac is carried by alcohol, which is polar. Oils and waxes are generally non-polar, so they find alternate paths into the wood and hold as they can. Unless you've got a fairly occlusive surface finish, shellac should do what you want.
 
Lankford The 2 finishes you mention are what I call low build finishes. That means it takes many coats to get the same kind of gloss that you would from Shellac, lacquer, Varnish etc. You could simply add some polyeurethane to the tung oil. I think I used to mix it 1part Poly to 7 parts tung oil. Then you apply as many coats as necessary to achieve the gloss you want. Friction polishes "build" a little better than tung oil so it takes fewer coats to get a good shine. I use the Beal polishing system with lacquer most of the time. I'm working on a hand mirror right now that I'm using True Oil. I'm not sure the contents but it's something like Varnish and oil. It builds very quickly. I'm on the 4th coat now (steel wool between each coat) and it's almost done. I would say 6 to 8 should do the trick. This is a very thick glossy finish used for gun stocks and that's why I thought I would use it. This mirror is made from Claro Walnut so I thought I would duplicate the gunstock look. I'm going to finish the next one with many coats of lacquer and look at the difference when I'm done.
