I've got rusty door hinges that came with my '55 F100. The doors are already off the truck, and the hinges are loose. The cab has been primed (though I'm not sure it's the right color primer for my end application/color choice). But my issue is that the hinges have some surface rust. I'd like to get this rust off and then blast them with some primer (or something else?), but I'm not sure of the best way to completely remove the rust. It doesn't appear to be too bad, but I don't want to grind the surface rust into the cab when I tighten them down. Suggestions? Am I overthinking this?
Sorry if this is posted in the wrong sub-forum. I wasn't sure the best place to post this, and I didn't find anything pertinent to my application, so I figured I'd start a new thread.
Thanks! My dad has a small media (soda?) blaster for small parts. I'll try vinegar overnight, then maybe some Coke (coca-cola, not Colombian Bam Bam), then my dad's blaster thing.
Any advice on a primer so they don't re-rust? Rattle-can is a must, as I do not have any spray equipment yet.
Is there a specified torque for these hinges (when attaching to the frame, or when attaching to the door)? Or is the official torque "a good umpf"?
When you get all done trying all these ideas and it still need more
than run it through the dish washer with cascade powdered soap.
If I was going to soak them I would use the acid stuff made to run
through coffee pots. Than still do the dish washer. It's just what has
worked for me. IDK
I would put Never Seize on the hinge bolts and get them
Good-N-Tight. I had a torque wrench that had that setting
at full pull.
If you want to chemically change the rust and get rid of it completely use Jasco rust treatment. I used it on my whole frame for my F-6 and what will happen is the rust will chemically change into a white powder or a black tarnish that you can wire brush off, then clean the surface with some degreaser or equivalent then dry and apply paint or primer. Using Jasco you pour some out in a bowl and take a paintbrush to coat the object and let it evaporate and dry on it's own preferably not in the sun or with a fan. Hope that helps.
