Surface rust advise, need you auto body guys

Posted
  • Staff

 I have some surface rust in different areas of my 2001 3500. I have tried to address some of it once and failed, the rust came back in a month or so. I used a wire wheel to remove any loose light rust, had pretty clean metal when finished, sprayed 2 coats of "rust converter" to stop any that wasn't removed. Then sprayed 2 coats of primer over that. The rust came back.

 I am not a body man but did this happen because I did not apply paint to seal the repair? I thought the primer would do that but I guess I was wrong.

 One day I would like to repaint the truck but for now I just want to do some touch up and fix any thing I can to keep her looking decent.

 Thanks for any input.

    OMG, those are Japanese beer cans.  I hope the truck doesn't morph into a Honda.

Primer does not seal out water or air.  If you want to leave it primer looking, you need to shoot clear over it.

 

I think that is what got you.  Try it again and use at least some rattle can enamel over the repair and see if that doesn't help. 

 

Take a look at more products.  I believe the rust converter is designed to take iron oxide and close its chains and make existing rust stop.  It will not prevent future rust from starting.  That is usually a different product (phosphoric acid IIRC)

 

Good luck!

Omg! Lol

 I will try redoing it but coating with paint and or clear coat when finished. 

 At some point I will be replacing some sheet metal also. Rockers, floor from bottom of the firewall to the front seat mount and the center section of the bed between the wheel wells. I think the goose neck hitch contributed to that rusting.
