Thank you all for your responses.
Dan, I appreciate your offer too. When I get the chance to strip the old paint, I will have a much better idea of just how bad the metal really is. I was in Auto Zone last evening and came across cans of sandable primer that fills in pitted metal for about $4.50 a can. Thus far, what I've stripped are my hinges and side access door. They have the pitting. I will try the primer on them and see how it goes. If that works and my side panels and doors are pitted, I will try it on them.
