This might be a difficult problem to treat. I would coat all plants that are not yet infected with neem oil so that they will remain pest free. As far as dealing with the Magnolia… Winter may kill most of them, and you can start fresh by using rosemary oil in water to water with. The tree will take this up and scale bugs will find the tree toxic to consume. If the infection does not subside this winter, then cutting the tree down may be the best option.

The sap is from the insect damage and can be washed off. All trees should be sprayed with neem oil to protect them from future infestation. I would also apply the rosemary water to these as well.
