Ok, I'll start by saying I don't have a Mig welder, or any way to weld up sheet metal just yet.
While sanding the old paint off of my '51 Chevy doors, I saw 2 rust holes I hadn't seen b4 in the doors. what I did was cleaned the inside of the door really good with sand paper and laquer thinner. then I mixed up some quick steel epoxy putty and pushed it around and into the effected holes until it came out the other side, and smoothed it out good on the inside.. then I waited for it to dry and then knocked it flat with 40 grit paper, and then finished off with a thin coat of filler.. Is this going to hold up?

If the holes are real small.

the biggest is about 1/2" in diamater


When my brother was doing his '90 Ranger he used whatever he could find as a backer. old hard blue foam insulation, siding, tin ect... of course all of that fell out.

Duraglass would be your friend here, if you can't weld them up.

The approved method of course is to cut out and replace the rust - but not everyone has these tools or a place and knowledge to do this work.

Another thing is there are areas where rust gets into, like pinch welds, that are nearly impossible to replace. I say - you do the best you can for the time and materials and $$ you have available.

Even with the best of repairs once rust starts it really doesn't stop. If you use the vehicle or it's outside all you can really is stay on top of it when it gets bad enough.

That's 'righter' than some of the things I've used!

You probably did OK, but it depends on where on the door the rust is. Rust is hard to stop, but having done some rustproofing years ago, I found that if you seal the air out of the rust, it will surely slow it down, if not stop it.

You cleaned the area around the rust. If you're satisfied with your prep, get some rust neutralizer and rust proofing (not undercoating) from someone who deals with body restoration stuff (like Eastwood,not Walmart) and coat the area well. That will give you the best protection.
