This is my first post but my car has some pretty serious rust here on lower doors I saw the rest are about the same I wondered if it's worth fixing? In michigan they are all like this now

 

If you can find good replacements, that will be significantly easier and less expensive.

 

It depends on how good of a welder you are.

 

Welder and sheet metal former...

 

I am not a very good welder and even if I was, I would replace them if I could find some decent ones.

 

Not worth it unless you can't find a better set. The doors on my cutlass looked exactly the same except the previous owner filled them in with a gallon of bondo. I could have repaired them just fine but, I just bought a better set.

 

Maybe post a wanted ad. List your location. See what's out there.
