Why not spray it with conformal coating first too?I learned a lesson from my two F150s:
2003 Harley F150: Radio antenna post rusted solid to the screw-in base.
2010 Raptor F150: I didn't learn from the '03, same antenna rust.
The first thing I'm going to do is is pull the radio antenna fender mount parts and glop it full of dielectric grease. And I'm gonna regrease it all at every oil change.
