I am using Watco satin finishing wax on a walnut project. I have been applying the product as instructed on the can twice a day for a week. I have been increasing the time up from the recommended 10 minutes before wiping. I have wet sanded with the wax. The problem I am having is: the finish isn't building up, actually the finish isn’t even there, because the wax has a mineral spirits base it seems to be evaporating away completely within 8 hours of application. I didn't use a grain sealer. The project has no end grain showing. Is this product designed for complete finishing? Is it better used in combination with something else? Will it ever build a finish?
