My driver has some rust, would it be better to replace it or repair?

 

It don't look that bad, I would repair it unless you are looking for a concours restore. As long as the outside of the door looks good, nobody sees the inside.

 

Thanks, that is what I was thinking. This is going to be a nice driver only.

 

No bad - I say try to repair it first. Once you grind out the rust, see what you have left. I am thinking you will have enough left to weld in some small hand-cut patch panels and make it look nice again. If you cannot weld them, try to find someone who can.
When done, clean the inside well and paint it all with POR15 to prevent future rusting.

 

i had similar rust issues patch panles ad panel bond where my choice of weapons for the repair. i recreated the seam line where the door skin is folded over by running a really smooth bead of seam sealer they sell wide flat tips for the seam sealer bottles. posted pics so you could get some ideas I had to make patch panels on both sides outside and in foir this repair.

 

Thanks for the pics, helps out. Nice work.
