I=99m sure Stoddard is the same as Varsol. It will not evapora te and leave dirt on the part like gas and is much safer. Of course it is a flammable fluid and should be treated as such, for exampl e disconnecting the battery, removing trouble lights, etc. or any potential ignition source particularly when using a spray gun. Stay safe.
