For many hobby collectors this is where you buy a good welder and learn how to weld. Of course a good $2.00 ice pick when you went car shopping would have avoided this, but since that is water under the bridge, you now get the choice of a functional repair - fiberglass or a correct repair of metal. Depends what you expect from the car for the next ten years including what you will eventually sell it for. Fiberglass all those areas would seriously devalue the car. But if that is of little concern, fiberglass can be a functional solution. There are structural concerns if there is too much damage to key metal areas that fiberglass would not solve. Welding sheet metal is a bit tricky, but practice will get you able to do so reasonably well. There are plenty of video on web to teach you how to do so. If you invest in welder, get good equipment not cheap stuff, including a very good helmet, not cheap HF stuff. You will need a welder, air tank, cart, helmet, air compressor, and grinding/cutting air tools plus other items.
These cars are just not worth the money if you have to pay someone else to do all the work. Additionally if you have rust in the area just exposed, you should expect more rust elsewhere in the body.
You need to decide why you are doing all this, are you a serial junk car collector, or do you really want to learn how to fix and take care of these machines. If you just want a nice MB,then sell all of them and buy a really good one to start with. It's not like we didn't warn you.
