Ok Charlee continue this tech until all surface is the same and smooth and blended. Stay way from the decals your clear coat of shellac is very thin. After you do this then we need to apply shellac to protect everything. I can see spots like water spots on the arm. This is and indication the machine was stored in a very hot place at some time. Try if you can get the spots to go away by this melting and blending. It will look better when we apply the shellac.
You may need to get some rest first.
