Rusted out hole in door jamb. Help Needed

[jec1521]

Hey guys,

So since I bought this truck in 2009, there was some paint bubbling up in the rear driver's side door jamb. never thought much of it, but recently it has completely rotted out, and now I have a hole there. The truck was in a rear end collision before I got it, I assume this has something to do with it.

Does anybody have any tips on fixing this? How did it get this much worse? Would this be cause by some sort of drainage blockage or something?

Thanks

It was cause by a poor quality repair.
It looks to me like that was where the quarter was spliced in and the "technician" never bothered to apply corrosion protection to the back side.
For shame.

First and foremost you have to get ALL the rust out of there. You will have to cut out at least two inches beyond the hole as it is right now.
Splice in fresh sheet metal and make sure you coat the inside.
Finish accordingly.

Thanks for the help. That is what I assumed as well.

Couple questions:

What should I use to coat the inside, and how can I get it on there? I don't have access to it from the other side.

Also, Is there any way to not use sheet metal/welding? I would like to try to do it myself, but dont have any body work experience. I was thinking of cutting all of the rust out, and using metal mesh and bondo to cover it.

Once its all repaired soak the back side with cavity wax pretty heavily.
This product from 3M works great.

No, there is no proper safe way with out sheet metal patching.

Metal mesh and bondo will have no structural integrity what so ever.

Sorry my friend
