I just got a 91 Ef sedan, the exterior can use some work and has some bad rust on the bottom sides of it, what can i do to fix this? Will bondo work since it is not that big? Pics are below. Thanks.

 

I think they have all you need here:

It is always better to replace a rusted panel when its possible. Sure, Bondo will hide anything you want it to, but its really not fixing the problem.

Just FYI, you can use a panel adhesive for most applications if you can't, or don't have access to a welder.

Always remove the rust as completely as you can, and use a rust converter on any that you cant completely cut out.

When you do use Bondo, try to keep it a maximum of 1/4 inch thick, and less is better. Much more, and it is just going to crack out on you. If you need to fill larger areas, consider fiberglass or a reinforced filler for those areas, with a think skim coat of Bondo over that.

 

Where can i get the metal to use the adhesive with? So what if i just grinded all the rust out and use bondo do you think it would crack the size i will need to put to fix it?

 

Bondo needs a backing material behind it.
If you just bondo you will be able to push your finger right through it when it's all said and done.
You can see if the link to fixmyrust has the exact part you need and use automotive adhesive for that.
Or, you can cut out the part that is rusted through and just cut up an old fender or something and fit a piece of metal in through the hole.
You weld it or adhesive it and then it shoudl sit a bit lower than the real surface of the car.
That's when you use Bondo.

 

Thanks man i'm gonna try to do that this weekend.
