I'm afraid that Dorland's wax will give you a flat finish, not a satin finish. If the area is already painted in final form, you can use Liquin to create a satin finish. I would mix one part Liquin with two parts of thinner and apply. After it dries, see if the result is what you want. If not, repeat this application until you get the satin finish you desire. By diluting the Liquin and using multiple coats, you will avoid getting too shiny a finish first time out. Of course you can add the Liquin to your paint, as mentioned above, if the area is not in final form, but I've always had trouble knowing how much to add. If you take this approach, DO try it on a practice piece first and see how it dries.
Good luck.
