No Miriam you wipe the oil off with naptha or lighter fluid. The alcohol will take the oil off but well remove what shellac is left on the decals. Ok lets stay away from the decals until we have smooth the shellac over the machine with out decals. With this method we are really redistributing the shellac not removeing it. But like I told Charlee if you are worried about the decals get some clear shellac spray and spray them then smooth the orange peel with the final smoothing or adding more shellac to the machine.
