1970 dart hood hinges

First clean the rust and grime from the hinges so they work smoothly and realize when you ad layers of primer and paint, it tends to keep them from working like they should. I realize you guys up North get some pretty ratty metal. First thing I do when i drag a new project home, is spray the heck out of the hinges with good rust penatrent and get it all working smoothly. Then clean and when painting them,remember you want them to work so be easy on all the primer/paint.
Never had your problem.
