Door pillar rust

So.
I saw some Bondo from previous owner and started cutting it back and it just kept going. Here's where I am at after removal.

Probably should have just left the Bondo.



Ideas on options ?

Thinking I want to put a face patch panel over it from front side (inside) and then just seal and smooth it with Bondo on front and back side.


Not best way but can't remove cab.

Re: Door pillar rust

If you can't cut it out and weld it up, you can always try to "epoxy" a patch to it. It won't last forever since that rust likely goes 4 inches in all directions. But the epoxy stuff works if you prep right.

They use it in the trucks episode, but 1/4 of the way through the vid:

Re: Door pillar rust

they make a patch panel for that, but if you want to go cheap weld in flat steel
remove the bolt in your hinge to see how much rust in the bolt area
the captured nut may just spin

Thats cool stuff. Still watching video.
I was wanting to just cut out a face plate and tack weld in place ..... then use an adhesive or bondo to sort of seal it from further rust.

Just not sure ifs thats feasible or a bad idea.

Yup.
Just mainly worried about not ahving the door align properly if I took that on. Also not quite sure how the inner and outer work together.

So ... was thinking best way to patch it up easily .... like a "face plate" to keep mositure out ..... and seal it so no further rust.

Then when truck is back on road - deal with it properly then at a shop ..... or just as a long weekend project. I know it will be easier now as have it torn apart ...... but if I patch it with a face plate then can tackle the paint and sheet metal as a bigger proect in a few years (remove cab.)

So just a few pieces of sheet metal over top --- tack it down ... bondo it out. That be enough to prevent further rust and corrosion if I cut out existing rust and treat prior etc. ?

thx

Re: Door pillar rust

Im actually doing this exact repair right now! I am replacing the rusted piece with a new one. I am also replacing the rusted step at the same time, so the hinge pocket is probably a little easier.

the moisture that rusts that area out comes from the cowl vent
there is no 'sealing it' unless you shave the cowl vent
remove all the leaves from the area behind the hinge and clear out the drain
pull the vent covers off and look on top of the shelf above the door
this is where leaves and pine needles gather to rust our trucks into oblivion

you should be able to run a hose into the cowl vent and have it all run out thru the drain forward of the lower hinge

Re: Door pillar rust

Dont quite get how all those parts go together from the diagram.

http://www.lmctruck.com/icatalog/ca/full.aspx?Page=15

Need mainly door hinge repair (part #14) panel I need. But if I started to tackle I think Im probably in for replacing Hinge piller lower and inner (#11 and #12)

Then not sure if in for more welding and body work an alignment problems than I want to take on. Rather than patch it as best I can ..... cut out the rust .... and if I get the truck running and enjoying it .... take the body off and do a full restore in a few years from now.

Having never done it before - seems making decisions is almost always my biggest roadblock unless I can find a step by step then more confident of whats involved to tackle etc.
