Any oil with a carrier (usually turp or a petroleum variant) will penetrate the previous finish, and if the solutions are comaptible, will set up well. The reason for a light steel-wooling on an old finish is to open it up to help the carrier penetrate, and clean off crud that has colleccted from handling.
Depending on the amount of handling, wer and tear, any finish will wear down and need a touch-up. The beauty of an oil finish is that once well established, the light wooling, and a thin coat are all that it needs unless there are dents. Dents can be raised with a damp washcloth over the dent, and heat from the point of Barb's steam ion (no steam necessary from the iron - Barb wil supply enough if she catches you using her iron
) Squeeze the cloth until no water will run out of it, and use just the tip of the iron. Check after 1-second "dabs" with the iron, until the dent is raised. This will also raise the grain around the dent area, and will require refinishing from fine sandpaper back down to steel wool, and 3-4 coats of oil to bring back what the steaming has taken out of the original oil build-up. The fellow who taught me this recommended it for any hardwood except birds-eye maple and very highly figured grains - said it could be disasterous, resulting in splits due to pressures and stresses in the wood.
