Depends where you live but most repairs should include excluding oxygen from the bare area. Personally I like to heat up grease and spray it. Also remember we live in an area with substantial rust belt problems. I wait until I have done the repair and used paint on the external surface. Then drill holes or whatever to gain access for my long applicator nozzle. The grease slows down the existing rust rate to almost nothing and protects the new metal.
We still have a three thousand pound output hydraulic pressure pump that is designed to spray a grease and graphite mixture. We used to buy it in thirty gallon barrels and the unit sat on top. I no longer think the barrels of product are available.
